Magnesium oxide is a raw material for smelting metallic magnesium, and its shape is white fine powder, which is odorless. Magnesium oxide powder can be divided into light magnesium oxide and heavy magnesium oxide. It is light in volume and white amorphous powder. It is odorless, tasteless and non-toxic. Hard to dissolve in pure water and organic solvents, solubility in water increases due to the presence of carbon dioxide. It is soluble in acid and is converted into crystal by high temperature burning. In the case of carbon dioxide in the air, it forms a double salt of magnesium carbonate, which is heavy in volume and is white or beige powder. It is easy to combine with water, and it is easy to absorb water and carbon dioxide in the exposed air. It is easy to gel and harden when mixed with magnesium chloride solution.

Industrial grade light burnt magnesia is mainly used in the production of magnesite products. Lightly burned magnesia and magnesium chloride aqueous solution in a certain ratio, can be gelled and hardened into a hardened body with certain physical and mechanical properties, called magnesite cement. As a new type of cement, magnesite cement has the advantages of light weight, high strength, fire and heat insulation, energy saving and environmental protection. It can be widely used in building materials, municipal, agricultural, machinery and other fields. With the industrial upgrading and the demand and development of high-tech functional materials market, we have developed and produced a series of high-tech fine magnesium oxide products, mainly used in advanced lubricating oil, advanced boots, alkali-grade, food grade, pharmaceutical, silicon steel grade. It is composed of nearly ten varieties including advanced electromagnetic grade and high-purity magnesium oxide.

Advanced Lubricating Grade Magnesium Oxide is mainly used as a cleaning agent, vanadium inhibitor and desulfurizer in advanced lubricating oil processing, which greatly improves the compactness and rheology of lubricating film and reduces ash. Lead removal and mercury removal reduce the environmental pollution of lubricating oil or fuel waste. Surface treated magnesium oxide can also be used as a complexing agent, chelating agent and carrier in the refining process, which is more conducive to product fractionation and improve product quality. Especially when heavy oil is burned, the addition of fly 0 can eliminate the damage of vanadium in the heavy oil to the furnace.

Food grade magnesia is used as a supplement for magnesium supplements in food supplements, color stabilizers, and pH adjusters. It is used as a decolorizer ice cream powder PH regulator when sucrose 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 magnesia can be used as an antacid and a laxative in the field of biopharmaceuticals as an antacid, adsorbent, desulfurizer, lead removal agent, complex filter aid, PH regulator, and inhibits and relieves gastric acid. More, 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 has good magnetic permeability (ie, has a large positive magnetic susceptibility) and excellent insulation properties (ie, conductivity can be as low as 10 to 14 us. m dense state). 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.

Advanced electromagnetic grade magnesia is used in wireless high frequency paramagnetic magnetic materials, magnetic rod antennas, magnetic cores of frequency modulation components, and the like. Instead of ferrite. It can be used in the fabrication of composite superconducting magnetic materials and also in the electronic magnetic industry. As a "soft magnetic material." It is also an ideal raw material for industrial enamels and ceramics. High-purity magnesium oxide has excellent alkali resistance and electrical insulation at high temperatures, high thermal expansion coefficient and high thermal conductivity, and is widely used as a high-temperature heat-resistant material.

In the field of ceramics, it is used as a raw material for translucent ceramic citrus pots, substrates, etc., in magnetic materials, electrical fields, magnetic material fillers, insulating material fillers, and various carriers. The thermal conductivity of the ceramic substrate is more than 2 times higher than that of alumina, and the loss of electrolyte is only l / 10 of alumina. It can also be used as a raw material for high-purity fused magnesia, which can be chemically used as "analytically pure" magnesium oxide.
