Application field

It is to determine sulfur and pyrite in coal and sulfur and arsenic in steel. Used as a standard for white pigments. Light magnesium oxide is mainly used as a raw material for preparing ceramics, enamels, refractory crucibles and refractory bricks. It is also used as a polishing agent, adhesive, coating, and paper filler, as an accelerator and activator for neoprene and fluororubber. After mixing with magnesium chloride and other solutions, it can be made into magnesium oxide water. Used in medicine as an antacid and laxative, for hyperacidity of the stomach and duodenal ulcer. Used in the chemical industry as a catalyst and a raw material for the manufacture of magnesium salts. It is also used in the manufacture of glazing, dyeing meal, phenolic plastic, etc. Heavy magnesia is used in the rice milling industry for firing, grinding and half-drum. The construction industry is used to manufacture artificial chemical floors, artificial marble heat-proof panels and sound-proof panels, and the plastic industry is used as filler. It can also be used to produce other magnesium salts.

One of the main uses of magnesium oxide is as a flame retardant. Traditional flame retardant materials are widely used in flame retardant mixtures composed of halogen-containing polymers or halogen-containing flame retardants.
