White or light yellow powder, odourless and tasteless, the goods insoluble in water or ethanol, slightly soluble in ethylene glycol, melting point 2852 ℃, 3600 ℃ boiling point, magnesium oxide have highly refractory insulation performance. The 1000 ℃ high temperature burning above can be into crystals, rose to 1500 ℃ above is dead and magnesium oxide or into sintered magnesia.
Used as the standard of white paint. Lightweight magnesium oxide mainly used for preparation ceramic, enamel, refractory crucible and refractory bricks of raw material. Also used for polishing agent bond url] coating] and paper packing, neoprene and fluorine rubber accelerator and activator. And magnesium chloride solution after mixing, can be made into magnesium oxide water tone. Medicine on an acid agent and used as a laxative, used for too much acid stomach and forefinger bowel ulcer disease. The chemical industry used as catalyst and manufacture magnesium salt of raw material. Also used to put out of glass, dye meal, phenolic plastic manufacturing. Heavy quality magnesium oxide milling industry for the fire grinding and half roller. Building industry used to make artificial chemical artificial marble floor heat resistant plate sound insulation board plastic industry used as filler. Also can be used in the production of other magnesium salt.
