When magnesite is calcined at 800-1200â??, it is called "light burning", and its product is called light burning magnesium powder, which is called light burning powder for short. Light-burned powder is mainly used to make cementitious materials, heat-insulating and sound-insulating building materials and ceramic raw materials, and it is also an ideal raw material for producing high-density magnesia. After chemical treatment, light-burned magnesium can be made into a variety of magnesium salts, which are used in magnesium sulfate, light magnesium oxide, inorganic glass fiber reinforced plastic, magnesium hydroxide, fire-proof board, magnesia-alumina spinel, light-weight wallboard, greenhouse bracket, ventilation pipeline, fire-resistant cable, magnesite manhole cover, mold, trailer, and so on.
