“Andalusite is a naturally occurring alumino-silicate mineral (Al2SiO5) that is commonly found in metamorphic rocks. It is known for its remarkable thermal stability, making it an important raw material in the refractory industry. Andalusite is used to produce high-temperature ceramics and refractory linings, which are essential for furnaces, kilns, and other industrial processes requiring resistance to thermal shock and mechanical stress. Additionally, due to its unique crystalline structure and variable color, andalusite is sometimes used as a gemstone in jewelry.”
