Magnesium oxide has a high degree of refractory insulation properties. It can be converted into crystals by burning at a temperature above 1000 ° C. When it is raised to 1500 - 2000 ° C, it is formed into a burnt magnesia (also known as magnesia) or sintered magnesia.
Food grade magnesium oxide
Application: It is used as a supplement for magnesium additives in food supplements, color stabilizers, and pH adjusters as health care products and foods. It is used as a decolorizer ice cream powder pH regulator when granulated sugar is refined. As an anti-caking agent and antacid used in the fields of wheat flour, milk powder chocolate, cocoa powder, grape powder, sugar powder, etc., it can also be used in the fields of ceramics, enamels, glass, dyes and the like.
Medical grade magnesium oxide
Application field: Bio-pharmaceutical field can use medical grade magnesia as antacid, adsorbent, desulfurizer, lead removal agent, complex filter aid, pH regulator. It is used as antacid and laxative in medicine, inhibition and alleviation. Excessive stomach acid, treatment of gastric ulcer and duodenal ulcer disease. Neutralizing gastric acid is strong, slow and long-lasting, and does not produce carbon dioxide.
Silicon steel grade magnesia
Application: Silicon steel grade magnesia has good magnetic permeability (ie, has a large positive magnetic susceptibility) and excellent insulation properties (ie, conductivity can be as low as 10-14 us/cm densification). The surface of the silicon steel sheet can be formed into a good insulating layer and a magnetic conductive medium to suppress and overcome the eddy current and skin effect loss (referred to as iron loss) of the silicon steel core in the transformer. Improve the insulation properties of silicon steel sheets and use them as high temperature annealing separators. It can also be used as a dephosphorization agent, a desulfurizer, and an insulating coating agent in silicon steel for ceramic materials, electronic materials, chemical raw materials, binders, and additives.
