Description :

Overview of Mullite

Mullite (CAS: 1302-93-8) is an important aluminosilicate ceramic material widely used in high-temperature industrial applications, refractory manufacturing, and advanced ceramics. It is a stable crystalline compound composed mainly of aluminum oxide and silicon dioxide, typically represented by the chemical formula 3Al₂O₃·2SiO₂.

Mullite is known for its excellent thermal stability, low thermal expansion, high mechanical strength, and strong resistance to chemical corrosion. Because of these properties, it is widely used in refractory linings, kiln furniture, furnace insulation, and ceramic structural components.

In advanced ceramic and refractory industries, materials such as Aluminum Oxide, Silicon Carbide, and Zirconium Oxide are also commonly used for high-temperature resistance, structural ceramics, and industrial refractory applications.
