Magnesium Oxide
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.
