Product Description

Aluminum hydroxide, white solid, insoluble in water, soluble in acid or alkali, is a typical amphoteric hydroxide. After heating and dehydration in air, it can be converted into alumina, which is of great significance for alumina production.



Aluminum hydroxide can react with acid to form salt and water, and with strong base to form salt and water, so it is an amphoteric hydroxide. It is also called aluminic acid (H3AlO3) due to its acidity. However, in fact, tetrahydroxyaluminate is generated when reacting with alkali. Therefore, it is usually regarded as metaaluminic acid monohydrate, which can be divided into industrial grade and pharmaceutical grade according to its use.
