【 magnesium aluminium spinel introduction 】 :

Magnesium aluminum spinel belongs to a kind of aluminum and magnesium oxide, the main components in aluminum oxide and magnesium oxide. Magnesium aluminum spinel has naturally occurring and synthetic two kinds, the former is MgAL2O4 or Mgo style, AL2O3. Spinel theory content is: MgO style = 28.3% M, AL2O3 = 71.7%. Natural magnesia spinel rarely found that magnesium aluminum spinel in industrial application are all synthetic. Synthesis of magnesium aluminium spinel and fused two main methods are sintering method. Most spinel material is made from high purity synthetic chemical and alumina grade magnesium oxide, which in shaft kiln sintering and fused in arc furnace.
