  1. Magnesium oxide

    Magnesium oxide, or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium. It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2− ions held together by ionic bonds. Magnesium hydroxide forms in the presence of water, but it can be reversed by heating it to separate moisture. Magnesium oxide was historically known as magnesia alba, to differentiate it from magnesia negra, a black mineral containing what is now known as manganese.
