Name: Activated Magnesium Oxide

English: Active magnesium oxide

Physical properties: active magnesium oxide, molecular formula MgO, relative molecular mass 40.30. Its chemical composition, physical form and other indicators are not much different from ordinary magnesium oxide, but some indicators of active magnesium oxide are different from ordinary magnesium oxide; if there is a suitable particle size distribution, the average particle size: <2 &micro ;m (2000nm); the microscopic morphology is irregular particles or nearly spherical particles or flaky crystals; the activity expressed by citric acid (CAA value) is 12~25s (the smaller the value, the higher the activity); expressed by the iodine absorption value The activity is 80~120 (mgI2/100gMgO); the specific surface is between 5~20m3/g, and the apparent volume is between 6~8.5mL/g. In addition, due to the high activity of this magnesium oxide, it is easy to absorb water, and sometimes it needs to be protected by chemical treatment. In some aspects, it exhibits special properties that conventional materials do not possess, so it is widely used as a new type of material.

Uses: Activated magnesium oxide is an important raw material for the preparation of high-function fine inorganic materials, electronic components, inks, and harmful gas adsorbents. It is expected to be developed as a cutting-edge material under harsh conditions such as high temperature and high corrosion. It can also be used as a filler for paint, paper and cosmetics, a filler and reinforcing agent for plastics and rubber, and an auxiliary material for various electronic materials.
