Magnesium Oxide

Magnesium Oxide Description

Magnesium Oxide (MgO) is an inorganic substance. It is a white solid at room temperature.

The magnesium oxide is used as a refractory under severe condition. Because its melting point (3098K) is the highest in the oxide and it is excellent in thermal conductivity (60W・m-1・K-1). The magnesium oxide is superior in corrosion resistance in the molten metal. The magnesium oxide can be used for a lot of metals compared with the aluminium oxide.
