Product Description
Magnesium oxide is an inorganic substance with the chemical formula MgO, which is an oxide of magnesium. It is a white solid at room temperature. Magnesium oxide exists in nature in the form of periclase and is a raw material for magnesium smelting.
Magnesium oxide has high refractory insulating properties. It can be transformed into crystals after high temperature burning above 1000°C, and it becomes dead-burned magnesia (magnesia) or sintered magnesia when it rises to 1500 - 2000°C.
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).
