Caustic Calcined Magnesite is also known as magnesia, bitter earth powder, light burnt magnesium powder, and its main component is mainly magnesium oxide. The natural magnesite ore is used as the main raw material, and is calcined at a temperature of 800 to 850 C. The color of the product is pink, yellow and white. Light burnt magnesium mainly manufactures cementitious materials, such as magnesium-containing cement. Thermal insulation and sound insulation construction materials, can also be used as ceramic raw materials. After chemical treatment of light burnt magnesium, can be made into a variety of magnesium salts, used as medicine. Rubber. Raw materials such as man-made fiber, papermaking, etc. Reburning magnesium. Most of the refractory materials used for metallurgy are used in the manufacture of magnesia bricks. chrome-magnesia bricks. Magnesia. Metallurgical powder. Electro-fused magnesium oxide is mainly used for smelting special alloy steel. Medium and high frequency induction furnace lining of non-ferrous metals and precious metals. Magnesium bismuth. It can also be used as high temperature electrical insulation material.
