Aluminum hydroxide

Aluminum hydroxide is a inorganic compound, chemical formula Al (OH) 3, which is the hydroxide of aluminum. Aluminum hydroxide is an amphoteric hydroxide that can react with acids to form salts and water, as well as strong bases to form salts and water. Due to its acidity, it can also be called aluminic acid (H3AlO3). However, in fact, when reacting with alkali, tetrahydroxy aluminate ([Al (OH) 4] -) is generated. Therefore, it is usually regarded as monohydrate of metaaluminic acid (HAlO2 · H2O), which can be divided into industrial grade and pharmaceutical grade according to its use.

1. Used as a flame retardant
Aluminum hydroxide filler is an ideal, environmentally friendly, and environmentally friendly flame retardant filler used for plastics and organic polymers.
2. Used as paper filler
Aluminum hydroxide fillers are mainly used as surface coatings, fillers, and in the production of non combustible paper in the papermaking industry.
3. Used as a toothpaste material
4. Used as a chemical raw material
Because aluminum hydroxide filler is a mass-produced, high-purity refined product that can dissolve quickly in strong acids and alkalis. Therefore, aluminum hydroxide filler is an important raw material for many types of aluminum salts.
