What are the uses of “magnesium oxide”?
Magnesium oxide is divided into two kinds: light magnesium oxide and heavy magnesium oxide. Light volume, white amorphous powder. Odorless, tasteless and non-toxic. Density 3.58g/cm3. insoluble in pure water and organic solvents, solubility in water increases due to the presence of carbon dioxide. Soluble in acid and ammonium salt solution. Transformed into crystals by burning at high temperature. When encountered with carbon dioxide in the air to generate magnesium carbonate compound salt. The heavy volume is compact, white or beige powder. It is easy to combine with water and absorb water and carbon dioxide easily when exposed to air. Mixed with magnesium chloride solution is easy to gelling and hardening.
Magnesium oxide classification use
Advanced lubricant grade magnesium oxide
Application areas: mainly used as detergent, vanadium inhibitor, desulfurization agent in advanced lubricant processing, greatly improve the denseness and rheology of lubricating film, reduce ash. It can also be used as complexing agent, chelating agent and carrier in oil refining process, which is more conducive to product fractionation and improve the quality of products. Especially in the heavy oil combustion when adding Mg0 can eliminate the heavy oil in vanadium acid damage to the furnace.
Food grade magnesium oxide
Application areas: used as food additive, color stabilizer, pH adjuster as health care products, food supplement of magnesium. Used as decolorizer for sugar refining ice cream powder pH regulator etc. As anti-caking agent and anti-acid agent for wheat flour, milk powder chocolate, cocoa powder, grape powder, sugar powder and other fields, also can be used in the manufacture of ceramics, enamel, glass, dyestuff and other fields.
Medical grade magnesium oxide
Application areas: medical grade magnesium oxide can be used as antacid, adsorbent, desulfurization agent, de-lead agent, complexing filtering agent, PH regulator in biopharmaceutical field, used as antacid and light laxative to inhibit and relieve excessive gastric acid, treat gastric ulcer and duodenal ulcer disease. Neutralize gastric acid with strong and slow and long-lasting effect, no carbon dioxide production.
Silicon steel grade magnesium oxide
Application areas: silicon steel grade magnesium oxide has good magnetic conductivity (i.e., has a large positive magnetization rate) and excellent insulating properties (i.e., conductivity can be as low as 10-14us/cm dense state). It can make the surface of silicon steel sheet form a good insulating layer and magnetic conductive medium to suppress and overcome the eddy current and skin effect loss (referred to as iron loss) of silicon steel core in transformer. Improve the insulating property of silicon steel sheet, used as high temperature annealing isolating agent. Also can be used as ceramic materials, electronic materials, chemical materials and binder, additives, etc. in silicon steel applied to dephosphorization agent, desulfurization agent, insulating coating generation agent.
Advanced electromagnetic grade magnesium oxide
Application areas: used in wireless high frequency paramagnetic permeability material, magnetic rod antenna, magnetic core of FM components, etc. Substitute for ferrite. Can be used in the production of composite superconducting magnetic materials, also used in the electronic magnetic industry. As “soft magnetic material”. It is also the ideal raw material for industrial enamel and ceramics.
High purity magnesium oxide
Application areas: high purity magnesium oxide has excellent alkali resistance and electrical insulation under high temperature. High coefficient of thermal expansion and thermal conductivity with good light transmission. It is widely used as high temperature heat resistant material. In the field of ceramics used as the raw material of light transmittance ceramic crucible, substrate, etc. In the field of electrical materials, electrical used as filler for magnetic devices, insulating material filler and various carriers. It can also be used as raw material of high purity electrofused magnesium sand, which can be used as “analytically pure” magnesium oxide in chemical industry.
