Dead-burned magnesium is refers to the magnesite in 1800 ℃ calcination, carbon dioxide completely escape, magnesium oxide periclase formed dense block, weighing burning magnesium (also called sintered magnesite), the dead-burned magnesium has the very high refractoriness. Its main ingredients for magnesium oxide, select natural super magnesite writing flotation purification, light burned, fine grinding, high pressure ball, ultra high temperature oil shaft kiln calcine.
Categories: light magnesium oxide and heavy magnesia two kinds. Light volume loose, white amorphous powder. Odourless, tasteless non-toxic. Density of 3. 58 g/cm3. Poorly soluble in water and organic solvents, solubility in water because of the existence of carbon dioxide. Soluble in acid, ammonium salt solution. After the high temperature burning into the crystals. When carbon dioxide from the air to generate magnesium carbonate double salts. Heavy volume, is white or yellowish powder. Easy to combine with water and air easy to absorb moisture and carbon dioxide. Mixed with magnesium chloride solution easy gelation hardening.
Widely used for plastic, resin, rubber, paint and other materials of the flame retardant filler, as well as the treatment of gastric acidity antacids, wastewater containing acid neutralizer, desulfurizer, sugar-refining, deodorant, etc. In addition it is also used in electronic industry, pharmaceutical, sugar refining, and making other magnesium compounds (such as magnesium sulfate and magnesium oxide).
Magnesium oxide (chemical formula: MgO style) of magnesium oxide, an ionic compound. Temperature is a white solid. Magnesium oxide magnesium Israeli stone form exists in nature, is the source of smelting magnesium.
Due to these calcination of magnesite products have different chemical properties and features, so the usage is different also. Light burning magnesium major manufacturing gelled material, such as magnesium cement, thermal insulation and sound insulation, building materials, also can do ceramic raw materials. After light burning magnesium chemical processing, can be made into many kinds of magnesium salt, used as a medicine, rubber, artificial fiber, paper and other aspects of the raw material
