Its major component is magnesium oxide (MgO) which is a kind of white oryellow powder, belonging to magnesia cement materials. Its main raw material comes from natural magnesite (MgCO 3 ) and can also be extracted from serpentine (3MgO•2SiO 2 •2H 2 O), dolomite (MgCO 3 •CaCO 3 ), molten slag produced by smelting magnesium alloy (the content of MgO is not less than 25 %), or seawater.
