Dolomite Powder is a double carbonate of magnesium & calcium having white colored appearance. It is widely utilized as a chief refractory material for furnace linings and in manufacturing of refractory bricks as well. In blast furnaces, it is used as a fluxing agent. By reacting calcined dolomite with sea water, magnesite can be produced. It has very high melting temperature of about 900 degrees Celsius. When used in furnaces or ladle, this compound can withstand temperature as high as 1700 degrees Celsius. Dolomite Powder is generally applied as outer lining in refractories for having low thermal conductivity.
