Heavy magnesium carbonate has a wide range of applications. my country’s high-end products are highly dependent on imports.

Heavy magnesium carbonate, also known as basic magnesium carbonate and medicinal magnesium carbonate, has a molecular formula of C2H2MgO6 and refers to an inorganic chemical product composed of hydrated salt-based magnesium carbonate or hydrated ortho-magnesium carbonate. Heavy magnesium carbonate appears as white powder, almost odorless, can make water weakly alkaline, and is insoluble in ethanol and water. Heavy magnesium carbonate has anti-caking and loosening properties and acid resistance, and is widely used in food additives, fireproof insulation materials, glass, medicine, coatings and other fields.

The main preparation methods of heavy magnesium carbonate include the caltropite metathesis method and the brine-soda ash method. The metathesis method of caltropite refers to using caltropite and ammonium sulfate solution as the main raw materials, mixing the two to undergo a metathesis reaction, and then going through processes such as recovery, precipitation, filtration, dehydration, and crushing to finally produce the finished product; brine-soda ash method It refers to using sodium carbonate solution as the main raw material, adding bittern, and finally making the finished product through processes such as precipitation, filtration, and drying. At present, my country’s medium and low-end heavy magnesium carbonate production technology has matured, and high-end products mainly rely on imports.

According to the “2023-2028 China Heavy Magnesium Carbonate Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , the global magnesium carbonate market size will reach 90 million yuan in 2022. As a subdivided product of magnesium carbonate, my country’s heavy magnesium carbonate market has maintained a stable development trend as a whole. In the future, driven by market demand, my country’s heavy magnesium carbonate production and sales are expected to further increase.

Heavy magnesium carbonate has a wide range of applications, including food additives, fire retardant insulation materials, glass, medicine, coatings and other fields. In the field of food additives, heavy magnesium carbonate can be used as a bread leavening agent and flour improver; in the field of fireproof and thermal insulation materials, heavy magnesium carbonate has high temperature resistance, heat insulation and other properties, and can be used as a raw material for fireproof bricks; in the pharmaceutical field , Heavy magnesium carbonate is an important pharmaceutical excipient, and aluminum magnesium carbonate chewable tablets are its end products, which can be used to treat conditions such as hyperacidity and duodenal ulcers. As the development of downstream industries accelerates, the scale of my country’s heavy magnesium carbonate market continues to expand.

The main manufacturers of heavy magnesium carbonate in my country include Hubei Hengjingrui Chemical Co., Ltd., Hebei Meixi Biological Co., Ltd., Hebei Meishen Technology Co., Ltd., Hebei Hongtao Bioengineering Co., Ltd., etc. At present, my country’s heavy magnesium carbonate production companies mainly produce mid-to-low-end products, while high-end products are dominated by overseas companies, including French Scora Company, Japan’s Kamijima Chemical Company, etc.

Industry analysts said that heavy magnesium carbonate, as a subdivided product of magnesium carbonate, has the characteristics of anti-caking and looseness and acid resistance. It has been widely used in many fields, and with the gradual release of market demand, my country’s heavy magnesium carbonate market prospects will continue to improve. At present, my country’s heavy magnesium carbonate enterprises mainly produce mid-to-low-end products, while high-end products rely on imports. This is the main challenge facing the development of the industry.
