Magnesium Oxide

Dense Magnesia 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. Morgan Technical Ceramics makes a range of lower density magnesia called Luminex.

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
