Physical properties of MgO

White light powder, odorless, tasteless, insoluble in water and ethanol, melting point 2852 ℃, boiling point 3600 ℃, Magnesium Oxide has high fire resistance and insulation properties. It can be transformed into crystal by high temperature sintering above 1000 ℃, and dead burned or sintered magnesia will be formed when the temperature is above 1500 ℃.

Chemical properties: magnesium oxide is an alkaline oxide with the general properties of basic oxide

Classification: Light Magnesium Oxide and heavy magnesium oxide. Light and fluffy, white amorphous powder. Odorless, tasteless and nontoxic. The density was 3.58 g / cm3. It is difficult to dissolve in pure water and organic solvents, and its solubility in water increases due to the presence of carbon dioxide. It is soluble in acid and ammonium salt solution. It is transformed into crystal by high temperature burning. In the presence of carbon dioxide in the air, magnesium carbonate is formed. It is white or beige powder with dense volume. It is easy to combine with water and absorb water and carbon dioxide in the open air. It is easy to gel and harden when mixed with magnesium chloride solution.
