Magnesia-alumina spinel

- Jun 12, 2019-

Magnesium-aluminum spinel is synthesized from high-temperature sintering or electrofusion of industrial alumina and light-burned magnesia. The chemical formula of magnesium aluminum spinel is MgO·Al 2 O 3 , wherein the MgO content is 28.2%, and the Al 2 O 3 content is 71.8%. It has the advantages of high temperature resistance, wear resistance, corrosion resistance, high melting point, low thermal expansion, low thermal stress, good thermal shock resistance, strong resistance to alkaline slag erosion and good electrical insulation properties.
