Magnesium carbonate is a white monoclinic crystalline or amorphous powder, non-toxic, tasteless, stable in the air, widely used.
Magnesium carbonate is used in the pigment, paint and printing ink industries, where magnesium carbonate is used to produce high purity magnesium compounds according to the needs of these industrial products. At the same time, magnesium carbonate is also used in refractories, fire extinguishing agents, flooring and insulation materials. In the plastics and rubber industries, magnesium carbonate is used as a filler and as a smoke inhibitor. In addition, in glass, ceramics and chemical production, chemical fertilizer also has a small number of applications. Food-grade magnesium carbonate is also used as a salt additive, powder forming foaming agent, and antacid in toothpaste and cookies.
Pharmaceutical grade magnesium carbonate is used as an antacid. Neutralizing gastric acid drug, clinical use for excessive gastric acid, gastric and duodenal ulcer. Because of its small mass and volume, it is suitable for preparing powder. In addition, it can also be used in the manufacture of magnesium salt, magnesium oxide, fireproof insulation materials, fireproof coatings, rubber, ceramics, glass, cosmetics, toothpaste and pigments and other industries. Food grade basic magnesium carbonate is mainly used as flour improver and magnesium element compensator. In the scientific formula of flour improvers, basic magnesium carbonate is an important auxiliary component, its important role is to improve the dispersion and fluidity of flour improvers, is an anti-caking loose agent, generally in the content of flour improvers is 10% to 15%. Have good liquidity. The MgO content is between 40% and 43%, the water content should be less than 1%, and the apparent specific volume is between 1.4 and 2.5mL/g. In addition, it is also used in food, cosmetics and medicine. In addition to being used as raw materials for electronic components, electronic-grade basic magnesium carbonate is also an important raw material for the preparation of high-purity magnesium oxide, advanced ink, fine ceramics, medicine, cosmetics, toothpaste, and high-grade pigments. Among them, the application of electronic materials has the highest added value.
Transparent light magnesium carbonate is mainly used as a filler and reinforcing agent for transparent or light-colored rubber products. After mixing with rubber, it hardly changes the refractive index of the rubber itself, and can enhance the wear resistance, flexure resistance and tensile strength of the rubber. It can be used as an additive in paints, inks and coatings, as well as in the toothpaste, pharmaceutical and cosmetic industries. Needle light magnesium carbonate is mainly used as rubber filler and reinforcing agent. Because its crystal shape is needle shape, easy to rubber bond, if its particle size and length-diameter ratio control is appropriate, its refractive index is close to rubber, its reinforcement transparency is good, can improve the rigidity of rubber, improve the flexibility. In addition, it can also be used in food, cosmetics and medicine. Block light magnesium carbonate is the same as light magnesium carbonate, only the shape of the product is a certain size of the block, currently used for athletes to wipe hands and absorb sweat.
