Cordierite

Its good thermal shock properties lend this material to be used in refractory applications. Its low thermal expansion and thermal conductivity make it a good choice for fixtures and other applications.

Cordierite is a Magnesium Alumina Silicate material. Its most important feature is that it has a very low coefficient of thermal expansion and excellent resistance to thermal shock. It is also similar to Steatite in that it is relatively low cost, has good electrical insulation properties, has moderate mechanical properties and temperature resistance, and can readily be formed in a variety of shapes. In particular it can be made in high volume through cost-effective extrusion or dry-pressing methods.

Key properties:

  • Low thermal expansion coefficient
  • High resistance to thermal shock
  • Volume resistivity
  • Low dielectric loss factor
  • Moderate strength
  • Low density

Applications:

  • Electrical insulators
  • Feed-thru insulators
  • High performance resistors
  • Special furnace shapes
  • Heating element supports
  • Exhaust catalyst supports
  • Burner tubes
