Application of magnesium carbonate and its development prospects

Magnesium carbonate is mainly used as a filler in rubber, plastics and other industries, and can be used in daily chemical products such as tooth powder, toothpaste, cosmetics, etc., and can also be used in the production of pharmaceutical food.

　　At present, the price of low-end magnesium carbonate in China's market is about 3,000 yuan / t, and the price of high-purity magnesium carbonate is tens of thousands of yuan / t. At present, the rubber industry is the largest user of magnesium carbonate in China, and its dosage accounts for about 30% of the total output of magnesium carbonate. In the domestic plastics market, the amount of magnesium carbonate accounts for about 15% of the total output of magnesium carbonate. The use of magnesium carbonate in other industries accounts for about 10% of the total.

　　Pharmaceutical food is the most potential application field of magnesium carbonate in China, and the amount of magnesium carbonate will grow steadily, and the market prospect is optimistic. Looking at the domestic magnesium carbonate market, the coastal economically developed areas of Jiangsu and Zhejiang centered on Shanghai have a high level of manufacturing of rubber, plastics, inks, and papermaking processing products, and the demand for magnesium carbonate is large and the quality requirements are high, and the main demand is high-purity magnesium carbonate, ultra-fine magnesium carbonate and other high value-added magnesium carbonate.

　　In addition, Zhejiang Hangzhou, Ningbo, Jiangsu Suzhou, Zhenjiang and other places, Guangdong Shenzhen, Dongguan and other places, plastic processing, toy production industry developed, the demand for magnesium carbonate is larger, mainly light magnesium carbonate and heavy magnesium carbonate, ultra-fine magnesium carbonate, high-purity magnesium carbonate also has a certain demand.

　　China is the world's magnesium carbonate resources and production power, now, magnesium carbonate is moving towards serialization, specialization, refinement, functional direction development. In recent years, China's demand for nanoscale ultrafine high purity magnesium carbonate is expected to grow at an annual rate of 15%. Several major industries such as plastics, rubber, medicine, and food in China have a large demand for nano magnesium carbonate.
