The main application of light burnt magnesium oxide powder

Light Burned Magnesia, also known as active magnesia or caustic magnesia, is magnesia formed by calcining magnesite ore at 700-900°C. Calcined Magnesium Oxide has a density of 2.94g/cm3, a melting point of 2852°C, and a boiling point of 3600°C. It is soluble in acids and ammonium salts, but hardly soluble in water and ethanol.

Light burnt magnesia is an important raw material for the preparation of high-functional fine inorganic materials, electronic components, inks, and harmful gas adsorbents. It is expected to be developed into cutting-edge materials under severe conditions such as high temperature and high corrosion. It can also be used as fillers for paints, paper and cosmetics, fillers and reinforcing agents for plastics and rubber, and auxiliary materials for various electronic materials.

In the building materials industry, it is used to produce magnesium sulfate, magnesium nitrate, Magnesium Hydroxide, etc.; in the pharmaceutical industry, it is used to prepare antacids and laxatives; it is mainly used as a decolorizing agent in the food processing industry.

Light burnt magnesia is the main raw material for magnesia cementitious products, used in the production of magnesium cementitious products. Combining light-burned magnesium oxide and magnesium chloride (magnesium sulfate) aqueous solution in a certain proportion can be gelled and hardened into a hardened body with certain physical and mechanical properties, so it is also called magnesium cement. As a new type of cement, magnesium cement has the advantages of light weight, high strength, fire resistance, heat insulation, energy saving and environmental protection. It can be widely used in building materials, municipal administration, agriculture, machinery and other fields, such as decorative panels, sanitary ware, ceilings, floor tiles, and ventilation ducts. , Anti-theft manhole covers, fire doors and windows, fire boards, partition boards, artificial marble, magnesium tiles, packing boxes, etc., as well as abrasive tools, stoves, fireworks fixing agents, etc.
