Magnesia powder
Magnesia powder is both an excellent electrical insulator and a very good thermal conductor. These properties are appreciated in the thermal industry as a component of thermocouples and heating systems. Available in 94% to 99.6% purity, these powders can be applied by dry pressing or injection moulding. Our powder grades vary depending on:
- Purity
 - Grain size and distribution
 
Applications of magnesia powder
- Manufacture of components for temperature measurement
 - Manufacture of thermocouple cables
 - Manufacture of heating and fire-resistant cables
 - Manufacture of heat cartridges
