The so-calledMagnesium hydroxideNot only a literal one, in fact, it can also be divided into two kinds of light magnesium oxide and heavy magnesium oxide.
Light magnesium oxide white amorphous powder, volume fluffy. It is difficult to dissolve in pure water and organic solvents, and its solubility in water increases due to the presence of carbon dioxide. Soluble in acid, ammonium salt solution. It is converted into crystals by high temperature burning. In case of carbon dioxide in the air, magnesium carbonate double salt is generated. Heavy magnesium oxide volume compact, white or beige powder. It is easy to combine with water, and it is easy to absorb moisture and carbon dioxide in the exposed air. It is easy to gel and harden when mixed with magnesium chloride solution.
In addition to their different physical and chemical properties, their application areas are not nearly similar.
Light magnesium oxide is mainly used as a raw material for the preparation of ceramics, enamel, refractory crucibles and refractory bricks. Also used as polishing agent adhesive and paper filler, chloroprene rubber and fluorine rubber accelerator and activator. After mixing with magnesium chloride and other solutions, it can be made into magnesium oxide water adjustment. It is used as an antacid and laxative in medicine, and is used for hyperacidity and gastro-intestinal ulcer. Used in the chemical industry as a catalyst and raw material for the manufacture of magnesium salts. It is also used in the manufacture of glass, dye meal, phenolic plastics, etc.
Heavy magnesium oxide is used in the rice milling industry for firing grinding and half rollers. The building industry is used in the manufacture of artificial chemical flooring artificial marble anti-insulation board sound insulation board plastic industry used as a filler. It can also be used to produce other magnesium salts. It is mainly used to formulate internal medicine to neutralize excessive stomach acid.
