Is light burned magnesium

Light burned magnesium oxide "and" active magnesium oxide "are different and belong to two concepts.
Light burned magnesium oxide: scientific name magnesium oxide.
It has a density of 2.94 and appears as a light yellow or white powder. Its melting point is 2852 ℃ and its boiling point is as high as 3600 ℃. It is soluble in acids and ammonium salts, but difficult to dissolve in water and ethanol. Easily deliquescent in the air. It belongs to the category of gas hard cementitious materials.
Active magnesium oxide, molecular formula MgO.
Its relative molecular weight is 40.30. Its chemical composition, physical form, and other indicators are not significantly different from ordinary magnesium oxide, but some indicators of active magnesium oxide require different requirements from ordinary magnesium oxide; If appropriate particle size distribution is required, average particle size:<2μ M (2000nm); The microscopic morphology is irregular particles or nearly spherical particles or sheet-like crystals; The activity represented by citric acid (CAA value) is 12-25 seconds (the smaller the value, the higher the activity); The activity expressed by iodine absorption value is 80-120 (mgI2/100gMgO); The specific surface area is between 5-20m3/g, and the apparent specific 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 requires chemical treatment to protect it.
In some aspects, it exhibits special properties that conventional materials do not possess, so it is widely used as a new type of material.
Purpose:
Activated magnesium oxide is an important raw material for preparing high-performance 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 paints, paper, and cosmetics, as a filler and reinforcing agent for plastics and rubber, and as an auxiliary material for various electronic materials.
Light burned magnesium oxide is a kind of light burned magnesium oxide obtained by calcining natural magnesite ore, brucite and magnesium hydroxide Mg (OH) 2 extracted from seawater or brine at 700~1000 ℃.
