Fused Magnesite

Fused magnesite is a highly refractory material that is produced by melting magnesite (magnesium carbonate, MgCO₃) at very high temperatures (over 2000° C) in an electric arc furnace. This process converts the material into magnesium oxide (MgO), which has a high purity and density. Fused magnesite is used in the steel and glass industry for refractory linings, in the chemical industry as a catalyst, and for the production of magnesium compounds, as well as in blast furnaces and cement kilns.
