Magnesia
Dense Magnesia (Magnesium Oxide) is not normally used as an engineering ceramic. However, lower density Magnesia, for example with 30% porosity, is used in a variety of applications due to its electrical and refractory properties.
Typical characteristics include:
- High temperature capability
- Low electrical conductivity
- High thermal conductivity
- Good corrosion resistance
- Infrared transparent
Typical applications include:
- Heating elements
- Thermocouple tubes
- High temperature crucibles
- Kiln furniture
