Sodium Meta Aluminate Powder (CAS 11138-49-1): High-Performance Al2Na2O4 for Industrial Water Treatment

We are pleased to offer Sodium Meta Aluminate Powder (CAS No. 11138-49-1, Molecular Formula: Al₂Na₂O₄), a high-purity inorganic compound widely used as a key water treatment chemical and industrial auxiliary agent. This white powder product delivers outstanding performance in coagulation, pH adjustment, and alkalinity control across a diverse range of industrial processes including municipal and industrial water treatment, papermaking, titanium dioxide production, and construction chemicals.

• Excellent Coagulation: Provides rapid and effective coagulation in water treatment processes, aiding in the removal of suspended solids, turbidity, and organic matter from both raw water and wastewater streams.
• Superior pH & Alkalinity Control: Delivers strong alkalinity adjustment capabilities, making it an efficient alternative to caustic soda and other alkaline agents in industrial pH control applications.
• High Purity & Consistency: Manufactured under strict quality control to ensure consistent chemical composition, particle size distribution, and performance from batch to batch.
• Versatile Industrial Applicability: Suitable for water treatment, papermaking, titanium dioxide manufacturing, zeolite synthesis, construction chemistry, and alumina production.
• Cost-Effective Solution: High active content and efficient dosing reduce chemical consumption and operational costs compared to alternative treatment chemicals.

Sodium meta aluminate serves as an effective coagulant aid in drinking water purification and industrial wastewater treatment. It enhances floc formation when used with primary coagulants such as aluminum sulfate or polyaluminum chloride (PAC), improving turbidity removal and reducing sludge volume. Its alkalinity contribution stabilizes pH throughout the treatment process without the need for separate alkali dosing.

In paper and pulp manufacturing, sodium meta aluminate is used in retention and drainage systems as well as specialty coatings and pigments. Its controlled alkalinity release improves fiber bonding and enhances paper strength properties.

Sodium meta aluminate plays a critical role in the surface treatment and coating of titanium dioxide (TiO₂) pigment particles, improving dispersibility, weather resistance, and optical performance in paints, coatings, plastics, and cosmetics.

Used as an accelerator and setting agent in cement and concrete formulations, sodium meta aluminate contributes to faster setting times and improved early strength development. It is also employed in specialty mortars, grouts, and waterproofing compounds.

As a reliable aluminum and sodium source, sodium meta aluminate is widely utilized in the hydrothermal synthesis of zeolites and molecular sieves for catalysis, adsorption, and ion-exchange applications.

Our sodium meta aluminate powder is produced under ISO-certified manufacturing protocols with comprehensive quality testing at every production stage. Each batch is analyzed for purity, particle size, solubility, and chemical composition before release. We offer flexible packaging options including 25 kg bags, 1,000 kg supersacks, and custom packaging upon request to meet the specific logistics and handling requirements of our global customers.
