Application

Sodium aluminate serves a pivotal role across numerous industrial applications due to its chemical properties. Primarily, it is utilized in the treatment of industrial and municipal water supplies, where it efficiently precipitates soluble phosphate in sewage, particularly in wastewater with low alkalinity. In the papermaking industry, sodium aluminate aids in improving sizing, filler retention, and minimizing pitch deposition, contributing to product quality. Moreover, when added to titanium dioxide paint pigments, it enhances the nonchalking performance of outdoor paints. Its versatility extends to the preparation of alumina-based catalysts and the synthesis of zeolites with improved silicon/aluminum ratios. Sodium aluminate facilitates the creation of porous crystalline aluminosilicates, which serve as effective adsorbents and catalyst supports, making it invaluable in the production of molecular sieves. However, it's essential to handle sodium aluminate cautiously, as it forms a strong corrosive alkaline solution when dissolved in water and is incompatible with certain metals and chemicals.
