Magnesium oxide, is an inorganic compound, chemical formula MgO, is an oxide of magnesium, is an ionic compound, white solid at room temperature. Magnesium oxide exists in nature in the form of magnesite and is a raw material for magnesium smelting.
Magnesium oxide has high fire resistance and insulation properties. After high temperature burning above 1000ºC can be converted into crystals, rise to 1500-2000 °C into dead burned magnesium oxide (magnesia) or sintered magnesium oxide.
Magnesium oxide is considered to be a refractory material that is physically and chemically stable at high temperatures. It has two useful properties: high thermal conductivity and low electrical conductivity. To date, the refractory industry consumes most of the world's magnesium oxide, in 2004, the refractory industry consumed about 56% of the United States magnesium oxide, the remaining 44% used in agricultural, chemical, building, environmental, and other industrial applications, [5] Magnesium oxide is used as a basic refractory in crucible.
Magnesium oxide is the main fireproof component in building materials. As a building material, magnesium oxide wallboard has several excellent characteristics: fire, termite-proof, moisture-proof, mildew proof and high strength.
