Alumina: Recommended for Nobel Metal Thermocouples since there are few impurities to react with Noble Metal Thermocouples at high Temperature. High physical strength. Good electrical properties. Fair resistance to thermal and electrical shock.

Mullite: Excellent high temperature material. Good Thermal Shock Resistance. Low Thermal Expansion.

Steatite: High physical strength. Good Electrical Properties. Loses resistance at high temperatures. Poor heat shock resistance.

Cordierite : Excellent heat shock resistance. Fair Physical strength and fair electrical properties.

Mullite, Steatite and Cordierite are recommended only for base metal thermocouples.
