Aluminiumsilicates
1-440.03.03Synonym: Aluminosilicate minerals;Aluminiumsilicates.
Chemical: Al2SiO5.MineralogyAluminosilicates are minerals composed of aluminium, silicon, and oxygen, plus countercations. They are a major component of kaolin and other clay minerals.
Andalusite, Kyanite, and Sillimanite are naturally occurring aluminosilicates. The triple point of the three polymorphs is located at a temperature of 500°C and a pressure of 0.4 GPa. These three minerals are commonly used as index minerals in metamorphic rocks.
