Aluminium hydroxide
Aluminium hydroxide is a chemical compound with the formula Al(OH)3. It is an inorganic compound that is commonly used as an antacid to neutralize excess stomach acid, as well as a component in the manufacture of various products, such as ceramics, paper, and cosmetics. It is a white, powdery substance that is insoluble in water and has a low toxicity. When heated, it decomposes to produce aluminium oxide, or alumina, which is used in the production of aluminium metal.
Aluminium silicate
Aluminium silicate is a compound made up of aluminium, silicon, and oxygen, with the chemical formula Al2SiO5. It is also known as kaolin, a naturally occurring clay mineral that is widely used in a variety of industrial applications. Aluminium silicate is valued for its high temperature resistance, low thermal expansion, and good electrical insulation properties, which make it useful in the manufacturing of ceramics, refractory materials, and insulators. It can also be used as a filler in paper, paint, and plastics.
