Active magnesium oxide, molecular formula MgO, relative molecular mass 40.30. Its chemical composition, physical morphology and other indexes are not much different from those of ordinary magnesium oxide, but some indexes of active magnesium oxide are different from those of ordinary magnesium oxide. If the particle size distribution is suitable, the average particle size is <2 μ M (2000 nm); The microscopic morphology is irregular particles or subspherical particles or lamellar crystals. The activity indicated by citric acid (CAA value) was 12~25s(the smaller the value, the higher the activity). The activity expressed by iodine absorption value was 80~120(mgi2/100gmgo). The specific surface is between 5~20m3/g, and the apparent specific capacity is between 6~ 8.5ml /g. In addition, due to the high activity of this magnesium oxide, easy water absorption, sometimes need to be chemical treatment to protect. As a new kind of material, it is widely used because it has some special properties that are not possessed by conventional materials.
Application: active magnesium oxide is an important raw material for the preparation of high functional fine inorganic materials, electronic components, ink and harmful gas adsorbents. It is expected to be developed as a sophisticated material under high temperature, high corrosion and other harsh conditions. It can also be used as a filler for paint, paper and cosmetics, as a filler for plastics and rubber, as a reinforcing agent and as an auxiliary material for various electronic materials.
