Mullite

Mullite is characterised by its excellent thermal and thermal shock resistance as well as particularly good creep resistance. Its coefficient of thermal expansion is roughly equivalent to that of a silicon semiconductor chip. Due to its low thermal expansion and excellent thermal stability, mullite retains its shape and strength even at high temperatures, making it ideal for applications in high-temperature technology. In addition, mullite offers good electrical insulation and low thermal conductivity, making it an outstanding material for electrical applications.

Applications of mullite are diverse, ranging from high-temperature technology and electrical insulation to the refractory industry.

The most important properties of Mullite (3Al₂O₃, 2SiO₂) in brief:

• High strength and hardness
