氧化镁 Magnesium oxide

                         氧化镁 

氧化镁是抗折、耐压、高强度、气硬、胶凝材料，广泛用于于国防、医药、化工、造纸、造船等行业。在建材工业上可制做胎子板、刨花板、保温立柱、栏杆、人造大理石、石棉瓦、普通瓦、墙板、铺设地面。随着科技的进步，氧化镁广泛用于沼气罐、大棚支架、工艺品、鞭炮、防火板等产品。

氧化镁（MgO）俗称菱苦土、轻烧粉、镁氧粉。密度2.94，白色粉末。熔点2852℃，沸点3600℃。溶于酸和铵盐，难溶于水和乙醇。煅烧温度400℃时比表面积为180m2/g。1300℃时比表面积仅为3m2/g。在空气中易潮解。它属于气硬性的胶结材料。

Magnesium oxide

Magnesium oxide is a flex-resistant, pressure-resistant, high-strength, gas-hard, cementitious material, which is widely used in national defense, medicine, chemical, papermaking, shipbuilding and other industries. In the building materials industry, it can be used to make placeboards, particleboards, thermal insulation columns, railings, artificial marble, asbestos tiles, ordinary tiles, wall panels, and flooring. With the advancement of science and technology, magnesium oxide is widely used in biogas tanks, greenhouse supports, crafts, firecrackers, fire boards and other products.

Magnesium oxide (MgO) is commonly known as bitter clay, light burnt powder, magnesium oxide powder. Density 2.94, white powder. The melting point is 2852 ° C and the boiling point is 3600 ° C. Soluble in acid and ammonium salts, hardly soluble in water and ethanol. The specific surface area at the calcination temperature of 400 ° C was 180 m2 / g. The specific surface area at 1300 ° C is only 3m2 / g. Deliquescence in the air. It belongs to gas hard cementing material.
