Magnesium oxide, or magnesia is a white solid mineral that occurs naturally as periclase and is a source of magnesium. It has empirical formula of Mgo. It is formed by an ionic bond between one magnesium and one oxygen atom. Magnesium oxide is easily made by burning magnesium ribbon which oxidizes in bright white light, resulting in a powder. It is hygroscopic in nature and care must be taken to protect it from moisture. The mineral known as dolomite is found as beds of rock also known as dolomite and as areas of mineral dolomite in lime stone. The magnesium oxide is used in grinding wheel, in medicine, for making cement in dry process plants; specifically Portland cement, as an insulator in industrial cables, as a basic refractory material for crucibles, in construction materials used for fireproofing, in feeding animals and there are special grades available, in leather processing. Magnesium oxide has good demand, so there is bright scope for new entrepreneurs to venture into this project.
