Magnesium aluminate spinel

  • Commodity name: Magnesium aluminate spinel
  • Commodity ID: 1070629134486097920
Electrically fused magnesium aluminum spinel is a new type of high-purity synthetic refractory raw material, which is made of alumina and high-purity light-burned magnesium oxide as the main elements in an electric arc furnace after being melted at a high temperature above 2000 ℃ and then cooled. There are mainly MA-65, MA-70 and other models, but also according to customer requirements to produce various types of fused magnesium aluminum spinel.

      Brief Introduction of Magnesium Aluminate Spinel Products

    Magnesia alumina spinel is a new type of high purity refractory material, which is made of high purity alumina and light burned magnesia in a certain ratio in an electric arc furnace after high temperature melting and cooling.

    Magnesium aluminum spinel color is white, with good crystallization, uniform structure, high volume density, strong anti erosion ability, high thermal shock stability, excellent performance, is a series of corundum refractory raw materials in the excellent refractory raw materials.The company's magnesium aluminum spinel can be made according to customer requirements of various sand and fine powder.

    Our magnesium aluminum spinel physical and chemical indicators are as follows:
