Commonly used magnesium oxide classification:
It is divided into light magnesium oxide and heavy magnesium oxide. Lightweight and loose, white amorphous powder. Odorless, tasteless and non-toxic. The density is 3.58 g/cm3. Hard to dissolve in pure water and organic solvents, the solubility in water increases due to the presence of carbon dioxide. Soluble in acid, ammonium salt solution. It is converted into crystals by high temperature burning. In the case of carbon dioxide in the air, it forms a double salt of magnesium carbonate. Heavy and compact, white or beige powder. It is easy to combine with water, and it is easy to absorb water and carbon dioxide in the exposed air. It is easy to gel and harden when mixed with magnesium chloride solution.
With the upgrading of industrialization and the demand and development of high-tech functional materials market, R&D has produced a series of high-tech fine magnesium oxide products, mainly used in advanced lubricating oil, advanced tanning base, food grade, medicine, silicon steel grade, advanced Electromagnetic grade, high-purity magnesium oxide and other nearly ten varieties.
