The Form of Sodium Metaaluminate

 

Liquid

The liquid sodium metaaluminate has appearance of light yellow viscous liquid and good solubility, and is a tasteless and strongly alkaline product. Used in water treatment plants, especially for large-scale operations where precise dosing and quick solubility are important.

Solid

The solid sodium metaaluminate appearance is white powder or fine particles. It is a colorless, odorless, tasteless, non-flammable, non-explosive and strongly alkaline product with good solubility, easy solubility in water, quick clarification, easy absorption of water and carbon dioxide in air, and easy precipitation of aluminium hydroxide after dissolution in water.

Application of Sodium Metaaluminate
 

Water treatment:
Sodium metaaluminate is utilized in water treatment processes, particularly in the clarification and purification of drinking water and wastewater. It helps to remove impurities, such as suspended solids and phosphates, by forming insoluble aluminum hydroxide flocs that can be easily separated by sedimentation or filtration.

 

Papermaking:
It is employed in the papermaking industry as a sizing agent to improve the water resistance and strength of paper products. Sodium metaaluminate reacts with rosin-based sizing agents to form a water-insoluble aluminum soap, which enhances the paper's resistance to penetration by water and other liquids.

 

Textile industry:
Sodium metaaluminate is used in textile processing as a mordant or dye-fixing agent to improve the colorfastness of dyed fabrics. It forms insoluble complexes with certain dyes, helping to fix them onto the textile fibers and prevent them from bleeding or fading during washing or exposure to light.

 

Catalysis:
It serves as a catalyst or catalyst precursor in various chemical reactions, including the production of zeolites, aluminosilicates, and other specialty chemicals. Sodium metaaluminate is involved in the synthesis of molecular sieves and catalyst supports used in petrochemical refining, environmental remediation, and organic synthesis.

 

Construction materials:
Sodium metaaluminate is used in the formulation of construction materials, such as cementitious grouts and mortars, where it acts as a setting accelerator or water-reducing agent. Its addition can improve the early strength development and workability of cement-based products, facilitating faster construction and reducing curing times.

 

Alumina production:
Sodium metaaluminate is a key intermediate in the production of alumina (aluminum oxide) from bauxite ore through the bayer process. It reacts with crushed bauxite in a high-temperature digestion process to dissolve aluminum hydroxide, which is subsequently precipitated and calcined to produce alumina for aluminum smelting.

FAQ
 

 

Q: Does sodium metaaluminate react with water?

A: Sodium metaaluminate reacts with water to form two hydroxides, sodium hydroxide and aluminium hydroxide. Note that the water used must be hot enough for the reaction to occur.

Q: What is the use of sodium metaaluminate?

A: 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 metaaluminate is employed to accelerate the solidification of concrete, mainly when working during frost.

Q: Does sodium metaaluminate dissolve in water?

A: Sodium metaaluminate will dissolve in water and produce a strong corrosive alkaline solution. May generate heat when water is added. Sodium metaaluminate generates a strong base in water; reacts violently with acids and corrosive to metals. Not compatible with copper, tin, zinc, aluminum, acids, phosphorus, or chlorocarbons.

Q: Is sodium metaaluminate a coagulant?

A: Sodium metaaluminate is an efficient, highly concentrated coagulant that can be used in water and wastewater treatment. The compound effectively removes solids, phosphates, turbidity and colour from water.

Q: What is the formula for sodium metaaluminate?

A: Chemical formula for sodium metaaluminate is NaAlO2, in hydrated form NaAl(OH)4, Na2O·Al2O3 or Na2Al2O4 in different structures. It is an inorganic compound which is utilized in numerous modern and mechanical applications as the best source of aluminium hydroxide.

Q: How is sodium metaaluminate produced?

A: Sodium metaaluminate is typically produced by the reaction of sodium hydroxide (NaOH) with aluminum hydroxide (Al(OH)₃) or aluminum oxide (Al₂O₃). This reaction forms sodium metaaluminate and water. This reaction takes place at a temperature of 900-1000°C.
