Magnesium oxide has high fire resistance and insulation properties. After being burned at high temperatures above 1000 ºC, it can transform into crystals. When it reaches 1500-2000 ° C, it becomes dead burned magnesium oxide (also known as magnesia sand) or sintered magnesium oxide.
Magnesium oxide melting point is 2852 ° C, the boiling point is 3600 ° C, and the density is 3.58g/cm3 (25 ° C). Soluble in acid and ammonium salt solution, insoluble in alcohol. Solubility in water is 0.00062 g/100 mL (0 °C), 0.0086 g/100 mL (30 °C).
