Magnesium oxide species

Classification: Light magnesium oxide and heavy magnesium oxide. Light weight, loose volume, white amorphous powder. It is odorless, odorless and non-toxic. The density was 3.58 g/cm 3. It is insoluble in pure water and organic solvents, and its solubility in water increases with the presence of carbon dioxide. It can dissolve in acid and ammonium salt solution. It is transformed into crystals by high temperature burning. When exposed to carbon dioxide in the air, magnesium carbonate compound is formed. Heavy compact, white or beige powder. It is easy to combine with water and absorb water and carbon dioxide in exposed air. It is easy to gel and harden when mixed with magnesium chloride solution.

With the upgrade of industrialization and the demand and development of high-tech functional materials market, a series of high-tech and fine magnesium oxide products have been developed and produced, which are mainly used in nearly ten varieties, such as high-grade lubricants, high-grade tanning alkali extraction, food-grade, medicine, silicon steel grade, high-grade electromagnetic grade, high-purity magnesium oxide and so on.

Magnesium oxide for desulfurization

Advanced Lubricant Magnesium Oxide

Application: Mainly used as detergent, vanadium inhibitor and desulfurizer in high-grade lubricating oil processing, which greatly improves the compactness and rheological properties of lubricating film and reduces ash content. Lead removal and mercury removal can reduce environmental pollution caused by lube oil or fuel waste. Magnesium oxide treated by surface treatment can also be used as complexing agent, chelating agent and carrier in refining process, which is more conducive to product fractionation and improve product quality. Especially when heavy oil is burned, adding Mg0 can eliminate the damage of vanadic acid in heavy oil to furnace.

Food grade magnesium oxide

Application: Used in food additives, color stabilizers, pH regulators as supplements of magnesium elements in health products and food. It can be used as decolorizer for sugar refining, ice cream powder PH regulator, etc. As anti-caking agent and anti-acid agent, it can be used in wheat flour, milk powder chocolate, cocoa powder, grape powder, sugar powder and other fields. It can also be used in the manufacture of ceramics, enamel, glass, dyes and other fields.

Medical grade magnesium oxide

Applications: In the field of biopharmaceuticals, medical magnesia can be used as acid-resisting agent, adsorbent, desulfurizing agent, lead-removing agent, complexing filter aid, PH regulator in medicine as acid-resisting agent and laxative to inhibit and alleviate hyperacidity of stomach and treat gastric ulcer and duodenal ulcer disease. Neutralizing gastric acid is strong, slow and persistent, and does not produce carbon dioxide.

Magnesium oxide of silicon steel grade

Applications: Magnesium oxide of silicon steel grade has good magnetic conductivity (i.e. high positive susceptibility) and excellent insulation performance (i.e. conductivity can be as low as 10-14us/cm dense state). Good insulating layer and magnetic conductive medium can be formed on the surface of silicon steel sheet to restrain and overcome the eddy current and skin effect loss of silicon steel core in transformer (referred to as iron loss). To improve the insulation performance of silicon steel sheet, it can be used as high temperature annealing isolator. It can also be used as ceramic materials, electronic materials, chemical raw materials, binders and additives in silicon steel for dephosphorization agent, desulfurization agent and insulating coating generator.

Advanced Electromagnetic Magnesium Oxide

Applications: For wireless high frequency paramagnetic permeability materials, magnetic rod antenna, magnetic core of FM components, etc. Replace ferrite. It can be used in the fabrication of composite superconducting magnetic materials, as well as in the electronic and magnetic industries. Make "soft magnetic material". It is also an ideal raw material for industrial enamel and ceramics.

High Purity Magnesium Oxide

Applications: High purity magnesium oxide has excellent alkali resistance and electrical insulation at high temperature. High thermal expansion coefficient and thermal conductivity have good light transmittance. It is widely used as high temperature heat resistant material. In the field of ceramics, it is used as raw materials for transparent ceramic crucibles, substrates, etc. in the field of electrical materials, magnetic device fillers, insulating material fillers and various carriers. The thermal conductivity of ceramic substrates is more than 2 times higher than that of alumina, and the loss of electrolyte is only 1/10 of that of alumina. It can also be used as raw material for high purity fused magnesia and as "analytical pure" magnesia in chemistry.

Nanometer magnesia

Applications: Nanometer magnesia has obvious small size effect, surface effect, quantum size effect and macro tunneling effect. After modification, it has no agglomeration. It has many special functions and important application value in optics, catalysis, magnetism, mechanics, chemical industry and so on. It has very broad prospects and is an important new material in the 21st century. Magnesium oxide nanoparticles are widely used in electronics, catalysis, ceramics, oil products, coatings and other fields. It has different functions in different products, such as flame retardants in chemical fibers and plastics industry; binders and additives in high temperature dewatering agents, advanced ceramics, electronic industrial materials and chemical raw materials in silicon steel sheet production; high frequency magnetic rod antenna in radio industry, magnetic device fillers, insulating materials fillers and various carriers; refractory fibers and refractories, magnesia chrome bricks, refractories. Fillers, high temperature resistant, insulating instruments, electrical, cable, optical materials and steelmaking for thermal coatings; electrical insulators, crucibles, melting furnaces, insulating conduits (tubular components), electrode rods, electrode sheets.
