Magnesium oxide classification: Magnesium oxide is divided into light magnesium oxide and heavy magnesium oxide
Magnesium oxide (lightweight) CAS: 1309-48-4 National standard: HG/T 2573-2012
It is mainly made of lightweight ceramics, with loose volume and white amorphous powder. Odorless, tasteless and non-toxic. Density 3.58g/cm3. It is difficult to dissolve in pure water and organic solvents, and its solubility in water is increased by the presence of carbon dioxide. Soluble in acid and ammonium salt solution. Transformed into crystals after high temperature burning. When meeting carbon dioxide in the air, it forms magnesium carbonate double salt
Magnesium oxide (heavy) CAS:1309-48-4 National standard: HG/T2679-2006
Magnesium oxide generally refers to heavy magnesium oxide, also known as lamp powder. White or beige powder. It is easy to absorb moisture and carbon dioxide when exposed to the air, and it is easy to gel and harden when mixed with magnesium chloride solution. The heavy volume is compact, and it is easy to combine with water, and it is easy to absorb moisture and carbon dioxide when exposed to the air. Easy to gel and harden when mixed with magnesium chloride solution
Heavy magnesium oxide is divided into light burnt and heavy burnt. The magnesite used in building materials belongs to the light burnt type of heavy magnesium oxide.
The difference between mild burn and severe burn
The main difference between the so-called light-burning and heavy-burning is the sintering temperature. When the sintering temperature is below 1200 degrees, generally speaking, the magnesia produced is light-burned magnesium oxide. When the sintering temperature reaches above 1200 degrees, the magnesium oxide produced is fired. Magnesium oxide is called dead burnt magnesium
