Light burned magnesia: its scientific name is magnesia. Light baking powder
Its density is 2.94 and it is light yellow or white powder. It has a melting point of 2852 ℃ and a boiling point of 3600 ℃. It is soluble in acids and ammonium salts, but not in water and ethanol. Easy to deliquescence in the air. The cementation material is hard gas.
Active magnesium oxide, molecular formula MgO
Its molecular weight is 40.30. The chemical composition, physical morphology and other indicators of active magnesium oxide are not much different from those of ordinary magnesium oxide, but some indicators of active magnesium oxide are different from those of ordinary magnesium oxide; The results showed that the activity was 12 ~ 25s (CAA value), 80 ~ 120 (mgi2 / 100gmgo) and 5 ~ 20m3 / g of specific surface and 6 ~ 8.5ml/g of apparent specific volume. In addition, due to its high activity and easy to absorb water, it sometimes needs to be protected by chemical treatment. In some aspects, it shows special properties that conventional materials do not have, so it is widely used as a new material.
Light baking powder
Application:
Active magnesium oxide is an important raw material for the preparation of high-performance fine inorganic materials, electronic components, ink and harmful gas adsorbent. It is expected to be developed as a cutting-edge material under high temperature, high corrosion and other harsh conditions. 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. Light burned magnesia is a kind of light burned magnesia obtained by calcining natural magnesite ore, brucite and Mg (OH) 2 extracted from seawater or brine at 700 ~ 1000 ℃.
Light burned magnesia
Light burned magnesia is used in chemical industry to produce magnesium sulfate, magnesium nitrate, magnesium hydroxide, etc., in pharmaceutical industry to prepare antacid and laxative, in food processing industry to decolorize, in glass and magnesium building materials industry, as the main raw material of glass and magnesium materials, it is mainly used in the production of glass and magnesium materials products Magnesium cement, as a new type of cement, has the advantages of light weight, high strength, fire prevention and heat insulation, energy saving and environmental protection. It can be widely used in building materials, municipal engineering, agriculture, machinery and other fields, such as decorative panels, partition boards, sanitary ware, ceiling, floor tiles , ventilation pipes, sewage well covers, fire doors and windows, fire boards, artificial stones, imitation wood products, roofing materials, handicrafts, abrasive molds, stoves, fireworks and so on.
