Customized MGO Magnesium Oxide 85%-99%  Industry Grade/Food Grade /Feed Grade/Pharmaceutical grade

Short Description:

Product Detail

Product Tags

Magnesium oxide is divided into two types: light magnesium oxide and heavy magnesium oxide. Lightweight and loose in volume, it is a white amorphous powder. Odorless, odorless, and non-toxic. Density 3.58g/cm3. It is difficult to dissolve in pure water and organic solvents, and its solubility in water increases due to the presence of carbon dioxide. Soluble in acid and ammonium salt solutions. Transformed into crystals by high-temperature burning. Generate magnesium carbonate complex salt when encountering carbon dioxide in the air. Heavy and compact in volume, it is a white or beige powder. It is easy to combine with water and absorb moisture and carbon dioxide when exposed to air. Mixing with magnesium chloride solution is easy to solidify and harden.

Multipurpose magnesium oxide

For the production of magnesite products, magnesite cement, as a new type of cement, has advantages such as lightweight, high strength, fire insulation, energy conservation and environmental protection. Silicon steel grade magnesium oxide is used in silicon steel as a dephosphorizing agent, desulfurization agent, and insulation coating generator. In the feed industry, it is used as a supplement for magnesium. Magnesium oxide flame retardant, with low smoke, low toxicity, and pollution-free properties

Advanced lubricating oil grade

Application field: Mainly used as a cleaning agent, vanadium suppressant, and desulfurizer in advanced lubricating oil processing, greatly improving the compactness and rheological properties of lubricating films, and reducing ash content. Removing lead and mercury can reduce environmental pollution caused by lubricating oil or fuel waste. Surface treated magnesium oxide can also be used as a complexing agent, chelating agent, and carrier in refining processes, which is more conducive to product fractionation and improving product quality. Especially when adding Mg0 during heavy oil combustion, it can eliminate the damage of vanadium acid in heavy oil to the furnace.

Food grade

Application field: Used as a supplement for magnesium in food additives, color stabilizers, and pH regulators as health products and food. Used as a decolorizing agent for sugar refining, ice cream powder, pH regulator, etc. As an anti caking and anti acid agent, it is used in fields such as wheat flour, milk powder chocolate, cocoa powder, grape powder, sugar powder, and can also be used in the manufacturing of ceramics, enamel, glass, dyes, and other fields.

Medical grade

Application field: In the biopharmaceutical field, medical grade magnesium oxide can be used as an antacid, adsorbent, desulfurizer, lead removal agent, chelating filter aid, and pH regulator. In medicine, it can be used as an antacid and laxative, inhibiting and alleviating excessive gastric acid, and treating gastric and duodenal ulcers. The neutralizing effect of gastric acid is strong and slow, lasting, and does not produce carbon dioxide.
