How To Reflect The Properties And Stability Of Sodium Aluminate
May 16, 2023
1. If used and stored according to the specifications, it will not decompose, and there is no known dangerous reaction. Avoid acid, carbon dioxide, moisture/humidity.
2. The high-temperature melting product is a white powder, easily soluble in water, and precipitates aluminum hydroxide after dissolving in water. The aqueous solution is alkaline and the pH value is 12.3. Insoluble in ethanol, easily absorbs moisture and carbon dioxide in the air.
Sodium aluminate is soluble in water but insoluble in alcohol. Hygroscopic. The aqueous solution is strongly alkaline and can gradually absorb water to form aluminum hydroxide, which is relatively stable when added with alkali or organic matter with many hydroxide groups. Reacts violently with acids and liberates gas with iron salts. Soluble in water, insoluble in alcohol. Widely used in the purification of industrial water and tap water, it can reduce the hardness of water and accelerate the settlement of suspended solids. Compounding with silicates can improve molecular sieve crystallization. It can be used as a catalyst and carrier for the conversion of petroleum hydrocarbons, as well as a raw material for the manufacture of amorphous alumina catalysts. It is also used to make a stable aluminum glue solution.
