Aluminum hydroxide is an inorganic substance with the chemical formula Al(OH)3, which is a hydroxide of aluminum. Aluminum hydroxide can react with acid to form salt and water as well as with strong base to form salt and water, so it is an amphoteric hydroxide. Since it shows a certain acidity, it can also be called aluminum acid (H3AlO3). However, the actual reaction with alkali produces tetrahydroxyaluminate ([Al(OH)4]-). Therefore, it is usually regarded as monohydrated meta-aluminic acid (HAlO2-H2O), which is classified into industrial grade and pharmaceutical grade according to its usage.

Aluminum Hydroxide

Aluminum hydroxide is the inorganic flame retardant additive with the largest amount and the most widely used. Aluminum hydroxide as a flame retardant not only can be flame retardant, but also can prevent smoke, do not produce drops and do not produce toxic gases, therefore, it has gained wider application and the usage is increasing year by year. Use range: thermosetting plastics, thermoplastics, synthetic rubber, coatings and building materials industries. At the same time, aluminum hydroxide is also the basic raw material of aluminum fluoride necessary for the electrolytic aluminum industry, and aluminum hydroxide is also very widely used in this industry.
