Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. 
Pure sodium aluminate (anhydrous) is a white crystalline solid having a formula variously given as NaAlO2, NaAl(OH)4 (hydrated),[2] Na2O·Al2O3, or Na2Al2O4. 
Commercial sodium aluminate is available as a solution or a solid.
Other related compounds, sometimes called sodium aluminate, prepared by reaction of Na2O and Al2O3 are Na5AlO4 which contains discrete AlO45− anions, Na7Al3O8 and Na17Al5O16 which contain complex polymeric anions, and NaAl11O17, once mistakenly believed to be β-alumina, a phase of aluminium oxide.

Anhydrous sodium aluminate, NaAlO2, contains a three-dimensional framework of corner linked AlO4 tetrahedra. 
The hydrated form NaAlO2·5/4H2O has layers of AlO4 tetrahedra joined into rings and the layers are held together by sodium ions and water molecules that hydrogen bond to O atoms in the AlO4 tetrahedra

Sodium aluminate is manufactured by the dissolution of aluminium hydroxide (Al(OH)3) in a caustic soda (NaOH) solution. 
Aluminium hydroxide (gibbsite) can be dissolved in 20–25% aqueous NaOH solution at a temperature near the boiling point. 
The use of more concentrated NaOH solutions leads to a semi-solid product. 
The process must be carried out in steam-heated vessels of nickel or steel, and the aluminium hydroxide should be boiled with approximately 50% aqueous caustic soda until a pulp forms. 
The final mixture has to be poured into a tank and cooled; a solid mass containing about 70% NaAlO2 then forms. 
After being crushed, this product is dehydrated in a rotary oven. 
The resulting product contains 90% NaAlO2 and 1% water, together with 1% free NaOH.

Reaction of aluminium metal and alkali
Sodium aluminate is also formed by the action of sodium hydroxide on elemental aluminium which is an amphoteric metal. 
The reaction is highly exothermic once established and is accompanied by the rapid evolution of hydrogen gas. 
The reaction is sometimes written as:

2Al + 2NaOH + 2H2O → 2NaAlO2 + 3H2
However, the species produced in solution is likely to contain the [Al(OH)4]− ion or perhaps the [Al(H2O)2(OH)4]− ion.

In water treatment it is used as an adjunct to water softening systems, as a coagulant aid to improve flocculation, and for removing dissolved silica and phosphates.

In construction technology, sodium aluminate is employed to accelerate the solidification of concrete, mainly when working during frost.

Sodium aluminate is also used in the paper industry, for fire brick production, alumina production and so forth.

Sodium aluminate solutions are intermediates in the production of zeolites

Sodium aluminate was introduced to the paper industry over 40 years ago. Its acceptance as an excellent wet end additive grew extensively in Europe and the U.S. paper making operations. Sodium aluminate was found to be very effective when used in conjunction with other cationic sources, such as alum, to optimize and improve wet end paper machine operations.

Simply stated, sodium aluminate is an alkaline form of aluminum which has been dissolved in caustic. Aluminum, because of its amphoteric nature, can be easily dissolved either in an acid or alkaline medium. Aluminum dissolved in sulfuric acid forms aluminum sulfate, or alum, and aluminum dissolved in caustic forms sodium aluminate. Sodium aluminate possesses an anionically charged alumina particle.

Sodium aluminate performs two basic functions in the paper maker process. One of these is primarily a chemical function which is to furnish a portion of the alumina required for sizing. Second function is best considered a physical function of coagulation and retention. System conditions created by these two reactions and the reaction products are the basis for the benefits provided by sodium aluminate.

Other benefits from sodium aluminate usage are:
Improved strength and durability
Cleaner machine system
Reduced foam
Reduced corrosion

Sodium aluminate
Sodium aluminate is a product obtained from the dissolution of aluminium hydroxide (gibbsite) in sodium hydroxide. 
ATAMAN CHEMICALS has sodium aluminates both in solution, in the form of powder.
Our Sodium Aluminates are an excellent source of reactive alumina in alkaline solution and this is the main reason for its use as a raw material in many industrial processes.

It is used in waste water treatment, it is a shotcrete set accelerator; it is also used in the paper industry as an auxiliary refining agent and retaining agent, and other uses are described as a raw material in catalytical supports, zeolites, etc.

Sodium Aluminate is immediately available in most volumes. 
Aluminates are compounds with a negatively-charged alumina ion and a metallic oxide with various industrial applications such as water treatment and ceramics manufacturing. 

Thanks to its product properties, sodium aluminate is an excellent precipitating agent.
In other words, it binds itself to unwanted substances in liquids as a result of a chemical reaction. 
In this case, the unwanted substance is phosphate. 
Sewage treatment plants use sodium aluminate to reduce the phosphate content in their wastewater – an extremely important process in wastewater treatment.

While SODIUM ALUMINATE is also used as a raw material in industrial production processes and by the construction sector, its primary use is in industrial wastewater treatment facilities and, above all, in sewage treatment plants. 
The product’s properties offer two clear advantages here. 
Thanks to its high pH value, SODIUM ALUMINATE helps prevent the formation of filamentous bacteria and so increases the overall efficiency and functionality of sewage treatment plants. 
What’s more, it acts as a precipitating agent and eliminates the phosphate in the water. 
This is important as high amounts of phosphate – which, in itself, is actually essential to life – can have a hugely negative impact on the environment. 
High levels of the nutrient, phosphorus, in rivers and lakes, for example, can result in a rapid growth of algae and water plants which, in turn, disrupts the ecosystem.

SODIUM ALUMINATE State-of-the-Art Water Purification Solution
All Sodium Aluminate solutions are produced according to EN 882 (Chemicals used for the treatment of water intended for human consumption). 
Aluminum products reduce chemical sludge production compared to iron, due to the low molecular weight of AI. 
Aluminates raise the alkalinity of the water, eliminating the need for lime or hydroxides.

SODIUM ALUMINATE is produced by reacting alumina hydroxide with sodium hydroxide. 
Our product is free of precipitates. 
Additionally, Sodium Aluminate has a very low content of heavy metals. 
The high content of AI in aluminates facilitates lowered transport costs.

Key benefits

Gives high purity and quality of water
Excellent coagulation, flotation and sedimentation
Increases alkalinity – no need for lime and hydroxides
Excellent removal of phosphor
Minimal chemical sludge
Low transportation cost

Sodium Aluminate is most widely used in municipal drinking water and waste water treatment systems. 
As an alkali, Sodium Aluminate can work in applications where the addition of caustic is not desirable. 
It provides an economical source of highly reactive alumina.

Sodium aluminate is becoming an increasingly popular choice for the removal of phosphorus in municipal and industrial wastewater plants. 
As discharge limits for nitrogen and phosphorus become more stringent, many plants are implementing both biological and chemical treatment systems for their reduction. 
However, both these treatment processes can deplete the available alkalinity and depress effluent pH below discharge limits.

Typical Applications
Typical uses of liquid Sodium Aluminate include the following:

Clarification in process and drinking water treatment applications
Clarification and phosphorus removal in wastewater treatment applications
Lime softening aid in process and groundwater treatment applications
pH adjustment and pitch control in paper mill applications
Surface treatment in titanium dioxide manufacturing applications
Synthetic zeolite and catalyst production
Refractory cement additives
Concrete additives
Industrial detergent compounds

Our Sodium Aluminate is high quality, consistent, high basic of aluminum. 
Due to the high pH of the product, many applications for sodium aluminate include co-coagulation with a more conventional coagulant.

The product can be used in many water and wastewater treatment applications, in papermaking, and as a raw material intermediate in commercial industries.

Sodium Aluminate is increasingly being used for drinking water and wastewater treatment. 
As an alkaline coagulant, sodium aluminate can be used for applications where the addition of caustic soda alone is not desirable. 
Sodium aluminate solution provides an economical source of highly reactive alumina.

Sodium Aluminate is becoming an increasingly popular choice for the removal of phosphates, magnesium, silicates, suspended solids (SS) etc. in municipal and industrial wastewater treatment plants as nitrogen and phosphate discharge limits become more and more stringent. 
Its use also improves water clarification by reducing corrosion, foaming and the amount of sludge generated. 
As a physico-chemical process with biological treatment or with the use of catalytic wet oxidation processes combined with the use of UV rays, the use of sodium aluminate creates real advantages.

This type of aluminium-based coagulant improves flocculation but is also used in other sectors:

In construction, as a concrete setting accelerator and as a hardening agent, especially when work is carried out in winter or during periods of frost
In the paper industry to increase the pH level
In the titanium dioxide industry for surface treatment, as intermediates

Abstract.  The  effect  of  sodium  aluminate  activator  on  properties  of  the  Portland-composite cement (clinker factor 65 %) was studied and the results are being discussed. 
It is shown that the introduction of sodium aluminate (Na[Al(OH)4]) leads to an  increase in the water demand of cement  and  a  decrease  in  its  strength.  
The  results  showed  that  the  sodium  aluminate  and polycarboxylate ether  (PCE) admixtures ensure  the  production of higher  strength  cements. 
It has been found that the addition of Na[Al(OH)4] – PCE significantly increases the compressive strength of cement mortar, particularly at 10–48 h of hydration. 
XRD and SEM measurements confirm that  the hydration of composite cement with the addition of Na[Al(OH)4] –  PCE is greatly accelerated by the  way of formation  of intense lines ettringite.  
It has been shown that the introduction of a sodium aluminate into the cement mortars allows to accelerate hardening and increase early strength and using of composite cement will provide improved performance and  suitability.  
The  results  have  shown  that  alkaline  accelerator  and  polycarboxylate  were effective for decrease shrinkage of composite cements. 

1.  Introduction Development  of  innovative  building  materials  is  one  of  the  priority  tasks  of  technological  and economic development in the construction industry. 
In recent years, due to the deep specialization of building construction, the market needs for chemical additives have increased, which allow to provide the  required  level  of  properties  of  cement  mortars  and  special-purpose  concrete  (high-strength, repaired,  waterproofing,  etc.).  
Modifiers  that  regulate  the  process  of  hardening  of  cement systems – accelerators of curing and hardening – should be singled out from various types of chemical functional  additives.  
Traditional  effective  accelerators  of  hardening  of  Portland  cement  include calcium chloride and alkali metal salts.  
However,  additives  containing  chlorine  ions currently have limited use, as chlorine ion promotes corrosion of the reinforcement. 
It should be also noted that a  number of alkaline accelerators, under certain conditions, can cause the destruction of concrete due to their  interaction with the active silica filler.  
Besides, alkaline hardening accelerators often reduce  the  final  strength  of  concrete.  
Therefore,  the  problem  of  finding  and  developing  effective hardening accelerators is particularly actual. 
Among  the  hardening  accelerators  for  cements,  additives  of  new  generation  based  on  active aluminium oxides can be singled out. 
The influence of sodium aluminate additive on the properties of building materials has been investigated by various researchers. 
These alkaline accelerators are important chemical additives for shotcrete concrete, which allow to shorten curing time from hours to minutes. 
The mechanism  of sodium aluminate action  in  the cement system is the  rapid  formation of the hydration product  of  calcium hydroaluminate (C-A-H), which  after  some time recrystallizes  into ettringite.  
It  was established that concretes made with the addition of  3–5  mass.  %  sodium aluminate have increased resistance to water. 
However, there is a decrease in the strength of concretes and mortars. 
At the same time, the introduction of a sodium aluminate accelerator greatly reduces the water  separation  in  mortars  and  concrete  mixes  and  prevents  corrosion  of  the  reinforcement.  
The introduction of an increased amount of aluminate component  in  the  composition  of  cement  leads  to increase  in  the  water  demand  of  the  binder.  
Such  technological  features  can  be  used  for systems requiring increased W/C  ratio in particular  in the composition of repair  materials, as well as for cement mortars destined for transportation, pouring and pumping. 
At the same time, such materials should be characterized by water resistance, which allows the frost resistance of concrete and mortars. 
Therefore, in order to reduce the water consumption of the mixtures and achieve their high fluidity, it is  advisable  to use  polycarboxylate  type  superplasticizers in  combination  with  alkaline  accelerators based on sodium aluminate. 
On the other hand, the impact of aggressive environment can lead to the rapid destruction of  building structures, so it is  advisable to  develop concretes and repair mortars using composite cements with a high content of mineral additives and fillers. 
It is necessary to study  alkaline  accelerators  based  on  sodium  aluminate to  achieve  high  technological  and  technical effects  in  obtaining  non-shrinkage  concretes  and  mortars  with  high  operational  properties  for rapid performance of reparation and restoration works

It is established that introduction of aluminium-containing alkaline activator in the Portland-composite cement CEM II/B-M (P-S-L) 32.5 R leads to the acceleration of curing time, increase in water demand and decrease in strength. 
The strength of CEM II/B-M with Na[Al(OH)4] – PCE supplements at an age of 1 day has increased by 3.2 time, at the age of 28 days – by 1.45 times higher. 
The optimal balance between  modifier  PCE  and  sodium  aluminate  that  realize  the  1  day,  28  and  90  days  compressive strength 16.7, 56.2 and 68.9 MPa are Na[Al(OH)4] – 1.5 mass. % and PСE –  1.2 mass. %. 
The linear shrinkage of cement mortar with  Na[Al(OH)4]  – PCE  supplements at an age of 2 and 90 days have been  decreased  by  4.5  and  2.2  times,  than  cement  mortar  without  additives.  
It  is  established  that sodium  aluminate  creates  the  possibility  of  obtaining  mortar  for  shotcrete,  as  well  as  quick performance of reparation and restoration works.
