It has an empirical formula of magnesium oxide,from Mg + ions and O₂The ions are bonded together by ionic bonds to form a crystal lattice, which in the presence of water forms magnesium hydroxide (MgO + H2O → Mg (OH)₂) However, magnesium hydroxide may in turn form magnesium oxide by heating to separate the water. Magnesium oxide is considered a refractory material, i.e. physically and chemically stable at high temperatures. It has two useful properties, high thermal conductivity and low electrical conductivity. To date, the refractory industry consumed most of the world's magnesium oxide, and in 2004, the refractory industry consumed about 56% of the magnesium oxide in the united states, with the remaining 44% being used for agricultural, chemical, construction, environmental and other industrial applications, with magnesium oxide being used as the basic refractory for crucibles.
