Application and Classification of Magnesium oxide powder bulk:

Magnesium oxide is a raw material for the treatment of magnesium metal. Its shape is white fine powder, odorless. Magnesium oxide powder can be divided into light magnesia and heavy magnesia, light volume, white amorphous powder, odorless, odorless, non-toxic, density of 3.58g/cm3. It is insoluble in pure water and organic solvents, and its solubility in water increases with the presence of carbon dioxide. It can be dissolved in acid and ammonium salt solution and 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.

Industrial grade light burnt magnesia is mainly used in the production of magnesite products. Light burnt magnesia and magnesium chloride aqueous solution in a certain proportion can be cemented and hardened into a hardened body with certain physical and mechanical properties, known as magnesite cement. As a new type of cement, magnesite cement has the advantages of light weight, high strength, fire prevention, heat insulation, energy saving and environmental protection, and can be widely used in building materials, municipal, agricultural, machinery and other fields. 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, food-grade, medicine, silicon steel grade, high-grade electromagnetic grade and high-purity magnesium oxide.


Magnesium oxide is mainly used as detergent, vanadium inhibitor and desulfurizer in the processing of high-grade lubricating oil, 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, integrator and carrier in refining process, which is more conducive to product fractionation and improve product quality. Especially when heavy oil is burned, adding MgO can eliminate the damage of vanadic acid in heavy oil to furnace.

Magnesium oxide powder bulk(Food grade magnesium oxide) is used as food additives, color stabilizers and 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, enamels, glass, dyes and other fields.

Medical magnesia can be used as antacid, adsorbent, desulfurizer, lead removal agent, complexing filter aid, PH regulator in the field of biopharmaceuticals as antiacid and laxative, inhibiting and alleviating excessive gastric acid, treating gastric ulcer and duodenal ulcer. Neutralizing gastric acid is strong, slow and persistent, and does not produce carbon dioxide.
