What are the differences between light burnt magnesia and active magnesia?

Light burnt magnesia: scientific name magnesia.

It has a density of 2.94 and is a light yellow or white powder. It has a melting point of 2852℃ and a boiling point of 3600℃. It is soluble in acids and ammonium, but insoluble in water and ethanol. Deliquescent easily in air. It is attributed to gas rigid cementation data.

Active magnesium oxide, the molecular formula MgO

Its molecular weight is 40.30. Its chemical composition, physical shape and other targets are not much different from those of ordinary magnesium oxide, but some targets of active magnesium oxide are different from those of ordinary magnesium oxide. For suitable particle size dispersion, uniform particle size: <2 m (2000nm); The microscopic shape is irregular grain or subspherical grain or flake crystal. The activity of citric acid (CAA value) was 12~25s (the smaller the value, the higher the activity). The activity indicated by iodine absorption value was 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 its high activity and simple water absorption, this magnesium oxide sometimes requires chemical treatment to maintain. As a new type of data, it has been widely used because of its special properties which are not available in conventional data in some aspects.

USES:

Active magnesium oxide is an important material for the preparation of high functional fine inorganic materials, electronic components, inks and harmful gas adsorbents. It is expected to be developed for high temperature, high corrosion and other severe conditions. It can also be used as fillers for paints, paper and cosmetics, fillers and consolidators for plastics and rubber, and auxiliary materials for various electronic materials. Light calcined magnesia is a kind of light calcined magnesia obtained from natural magnesite, brucite and magnesium hydroxide Mg(OH)2 extracted from sea water or brine by calcination at 700~1000℃.
