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.
