Industrial Materials Sector:
Refractory Materials: Magnesium carbonate is a key raw material for producing magnesia-based refractories, such as magnesite bricks and magnesia-alumina bricks. After being calcined at high temperatures and converted into magnesium oxide, it enhances the high-temperature resistance and mechanical strength of the refractory materials.
Thermal Insulation Materials: It serves as thermal insulation for boilers and piping, and acts as an important chemical raw material in the manufacturing of wires and cables.
Fillers and Desiccants: In the industrial materials industry, it is frequently used as a filler, desiccant, or buffering agent, helping to improve the performance and quality of industrial materials.
Food Industry:
Additives: Magnesium carbonate serves various functions, including as a flour treatment agent, anti-caking agent, leavening agent, drying agent, color retention agent, and carrier. When added to flour, it keeps the flour loose, prevents clumping, and helps modify dough properties. my country's *Hygienic Standards for Uses of Food Additives* permit the use of magnesium carbonate in wheat flour at a maximum level of 1.5 g/kg. FAO/WHO regulations allow its use as an anti-caking agent in milk powder and cream powder at maximum levels of 10 g/kg and 1 g/kg, respectively (used alone or in combination with other anti-caking agents; starch-free formulations only); it is also permitted for use in products such as chocolate and cocoa powder.
Magnesium Supplement: Magnesium carbonate is added to certain foods to help meet the human body's magnesium requirements.
Glass Manufacturing: In the glass industry-particularly in the production of LCD glass and glass-ceramics-magnesium carbonate acts as a fining agent to remove bubbles, ensuring the quality of the glass products.
Paper Industry: It serves as a filler and retention aid, enhancing the quality and performance of the paper.
Electronic Ceramics: Thanks to its excellent dielectric and mechanical properties, it is a key material in the manufacture of high-performance electronic ceramics.
Agriculture: It is used as a soil conditioner to adjust soil pH, improve soil fertility, and promote crop growth.
Sports: It is used as a drying agent for athletes' hands during competition, helping them perform at their best.
