Classification and use of magnesium oxide

Magnesium Oxide, as a kind of chemical raw material, has a wide range of uses and occupies a fairly important position in the national economy. In plastics, rubber, paint, enamel, man-made fibers, refractories and other industries have a wide range of applications. At the same time, Magnesium Oxide or metallurgical industry and other high temperature industry indispensable high temperature, refractory materials, commonly used in the manufacture of magnesium carbon bricks, magnesium bricks, crucibles, enamel, ceramics and so on. Or as a filler used in abrasives, paint manufacturing; in man-made fibers, rubber, such as fluoroelastomer, neoprene rubber as a catalyst and accelerator.

In the food industry as a decolorant applied to sugar refining, and in the production of ice cream as a ph regulator, etc.; in medicine with the role of antacid and diarrhea, mostly used in the treatment of duodenal and gastric ulcers, gastric acid overload; in agriculture as fertilizers and livestock feed to supplement the main regulating elements of plants and animals of magnesium; in the construction industry, the addition of magnesium oxide can be manufactured with magnesium-containing special sludge and thermal insulation boards; in the environmental protection, it can be used in the flue gas and gasoline, and can be used in the manufacture of ceramics, ceramics, and so on. Environmental protection, can be used for flue gas dust removal and desulfurization, water treatment and so on. Magnesium oxide also has a wide range of applications in the chemical industry, silicon steel, glass, electronics and other industries.

According to the use, magnesium oxide can be divided into active magnesium oxide, medical plug special magnesium oxide, silicon steel magnesium oxide, electrofusion magnesium oxide; according to the purity and other characteristics, magnesium oxide can be divided into Industrial Magnesium Oxide, High Purity Magnesium Oxide, heavy magnesium oxide, nano-magnesium oxide, calcined magnesium oxide and magnesium oxide whiskers and other kinds of species.

Secondly, the product when magnesium oxide is produced by wet method by making soda ash and ammonium carbonate as precipitating agent is basic Magnesium Carbonate. Magnesium basic carbonate is divided into many kinds, according to the use can be divided into food grade magnesium basic carbonate, medicine magnesium basic carbonate, electronic grade magnesium basic carbonate, etc.; According to different shapes, it can be divided into block magnesium basic carbonate, needle-shaped magnesium basic carbonate, amorphous magnesium basic carbonate, transparent lightweight magnesium basic carbonate and so on. Magnesium basic carbonate is calcined and decomposed to remove the water of crystallization and decompose CO2, according to the different calcination temperature and time, it generates magnesium oxide products with different activities and particle sizes as well as other physical characteristics.

Ultrafine high-activity magnesium oxide can be used as a highly efficient dissociative adsorbent for adsorption of toxic chemicals, such as organophosphates, because of its high surface chemical activity and strong adsorption.

High Purity Magnesium Oxide can be used in pharmaceuticals and paints, as an additive in food and feed, as a catalyst carrier, as an additive in the production of enamels and ceramics, and as a high-level insulating material. In addition to the special magnesium oxide for friction materials and silicon steel grade magnesium oxide for the iron and steel industry, magnesium oxide also has important applications in the field of national defense, military industry and aerospace.
