氧化鎂 Magnesium oxide

                         氧化鎂 

氧化鎂是抗折、耐壓、高強度、氣硬、膠凝材料，廣泛用于于國防、醫藥、化工、造紙、造船等行業。在建材工業上可制做胎子板、刨花板、保溫立柱、欄桿、人造大理石、石棉瓦、普通瓦、墻板、鋪設地面。隨著科技的進步，氧化鎂廣泛用于沼氣罐、大棚支架、工藝品、鞭炮、防火板等產品。

氧化鎂（MgO）俗稱菱苦土、輕燒粉、鎂氧粉。密度2.94，白色粉末。熔點2852℃，沸點3600℃。溶于酸和銨鹽，難溶于水和乙醇。煅燒溫度400℃時比表面積為180m2/g。1300℃時比表面積僅為3m2/g。在空氣中易潮解。它屬于氣硬性的膠結材料。

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.
