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 magnesia powder
- Manufacture of components for temperature measurement
- Manufacture of thermocouple cables
- Manufacture of heating and fire-resistant cables
- Manufacture of heat cartridges
