Aluminum hydroxide, the chemical formula Al (OH) 3, is a 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, so it is a kind of amphoteric hydroxide. Chemical formula Al (OH) 3, is a hydroxide of aluminum. Is a base, because it was a certain degree of acidity, it can be called aluminate (H3AlO3), but the actual reaction with alkali generated is meta-aluminate Salt, so it is usually regarded as a monohydrated meta-aluminate (HAlO2 • H2O), according to use is divided into industrial grade and pharmaceutical grade two. Aluminum hydroxide is white powder, the appearance of white crystalline powder, non-toxic, tasteless, good liquidity, high whiteness, alkali, iron content is low.

Aluminum hydroxide Usage: Aluminum hydroxide is the largest amount and the most widely used inorganic flame retardant additives. Aluminum hydroxide as a flame retardant can not only be flame retardant, but also to prevent smoke, do not produce drip, do not produce toxic gases, therefore, access to a wider range of applications, the use of the year also increased.

The use of aluminum hydroxide （CAS No.: 21645-51-2  MF:AL(OH)3）

1 aluminium hydroxide as water treatment, catalyst and catalyst carrier. 
2 aluminium hydroxide flame retardant in resin, synthetic rubber and plastic industry.
3 aluminium hydroxide in glass industry to increase whiteness, transparency, glossiness and brightness.
4 aluminium hydroxide in production of waterproof fabric, printing ink, paper filler, wires and cables.
5 aluminium hydroxide as mordant in dye/painting industry for its strong adsorption capacity of coloring matter.
6 aluminium hydroxide as ceramic material.
