Magnesium oxide is commonly known as bitter earth, also known as magnesium oxide. It is a typical alkaline earth metal oxide, chemical formula MgO. white powder, melting point is 2852ºC, boiling point is 3600ºC, relative density is 3.58(25ºC). Soluble in acid and ammonium salt solution. Slowly acts with water to form magnesium hydroxide. Can dissolve in carbon dioxide aqueous solution to produce magnesium bicarbonate. In the air can gradually absorb water and carbon dioxide, heating to release irritating fumes. Magnesite (MgCO3), dolomite (MgCO3-CaCO3) and seawater are the main raw materials for the production of magnesium oxide. Thermal decomposition of magnesite or dolomite yields magnesium oxide. With slaked lime treatment of seawater to get magnesium hydroxide precipitation, burning magnesium hydroxide to get magnesium oxide. Magnesium oxide in magnesium compounds in the production of the largest, accounting for all the magnesium industry products Chemicalbook 3/4. below 900 ºC produced magnesium oxide for the light magnesium oxide, density is small, the specific surface area is large, strong adsorption. It can be used as catalyst, rubber filler and accelerator to improve rubber performance. Mixed with magnesium chloride solution to make magnesium cement. Used as flame retardant for building materials. Medically used as antacid and laxative, used for hyperacidity and gastric and duodenal ulcer disease, often used in conjunction with constipation-prone calcium carbonate. Used as animal feed additive and plant fertiliser. In 950 ~ 1050 ºC produced lightweight magnesium oxide density, particle distribution has a certain range, easier to combine with water. Using it at high temperature and silicon steel surface of the silicon dioxide reaction, the generation of magnesium silicate film nature, can be used as a silicon steel plate isolation agent, to prevent the sintering of silicon steel plate in high temperature treatment of adhesion. Produced at a high temperature of 1500 ~ 1800 ºC heavy magnesium oxide density, small specific surface area, heat is not easy to decompose, low chemical activity, not easy to react with acid, low hydration rate. It is used as high-temperature refractory material, binder for manufacturing refractory crucible and furnace lining.
