Basic overview

Aluminum hydroxide is an inorganic substance. The chemical formula Al(OH)₃ is the hydroxide of aluminum. Aluminum hydroxide can react with acid to form salt and water, and can react with strong alkali to form salt and water. Therefore, it is an amphoteric hydroxide. Because it is also acidic, it can also be called aluminic acid (H₃AlO₃). However, tetrahydroxyaluminate （[Al(OH)₄]-） is actually generated when reacting with alkali. Therefore, it is usually regarded as metaaluminic acid monohydrate （HAlO₂·H₂O）, which can be divided into industrial grade and pharmaceutical grade according to its use.

Application

5N 99.999% high purity aluminum hydroxide powder is the most widely used inorganic flame retardant additive. As a flame retardant, aluminum hydroxide can not only be flame retardant, but also prevent smoking, no dripping and no toxic gas. Therefore, it has been widely used, and its use is increasing year by year. Scope of application: thermosetting plastics, thermoplastics, synthetic rubber, coatings, building materials and other industries. At the same time, aluminum hydroxide is also the basic raw material of aluminum fluoride necessary for electrolytic aluminum industry, and aluminum hydroxide is also widely used in this industry
