MgO – magnesium oxide

Everybody is familiar with magnesia – the white “adhesive” that athletes spread over their hands to prevent slipping during exercises. Magnesium oxide occurs naturally as the volcanic Mineral Periclase. Dense or porous sintered magnesium oxide (sintered magnesia) is used as a technical ceramic.

A noteworthy characteristic of this material is excellent electrical insulation and simultaneously high thermal conductivity (in densely sintered condition) and high temperature resistance up to approx. 2700 °C. Components made of MgO are for this reason preferred for refractory ceramics, as furnace lining, for laboratory appliances or as filler when shaping metal pipes in the production of tubular radiators, immersion heaters und heating elements.
