my country’s calcium carbonate output is gradually increasing, and leading companies are gradually emerging.

The chemical formula of calcium carbonate is CaCO₃. It appears as a white crystal under normal temperature and pressure. It is almost insoluble in water and can react with acid to release carbon dioxide. It is a very important functional powder material and inorganic chemical product. With the continuous advancement of calcium carbonate production technology in my country, product types are becoming increasingly rich and have various classification methods. According to the average particle size, calcium carbonate can be roughly divided into ultrafine calcium carbonate, particulate calcium carbonate, etc.; according to different production methods, calcium carbonate can be roughly divided into colloidal calcium carbonate, heavy calcium carbonate, light calcium carbonate, crystal carbonate Calcium etc.

From the downstream of the industrial chain, calcium carbonate has a wide range of applications and is widely used in papermaking, rubber, sealants, daily chemicals, inks, plastics, food, medicine, aerospace technology, architectural coatings, paints and other fields. Among them, plastics have become the largest application field of calcium carbonate, with a market share of 32.9%; followed by the papermaking field, with a market share of 29.7%; ranking third is the coating field, with a market share of 12.4%.

In recent years, my country’s economy and society have developed rapidly, residents’ income levels have increased steadily, and the requirements for daily necessities have gradually changed from practicality to both aesthetics and practicality. Plastic products have the advantages of rich shapes, bright colors, and high cost performance. They cover almost all walks of life in society and have a relatively high market penetration rate. However, as my country’s environmental protection requirements gradually increase and policies such as plastic restriction orders are gradually implemented, the demand for plastic products gradually declines. Against this background, the output of plastic products in my country has gradually declined. According to data released by the Ministry of Industry and Information Technology, the output of my country’s plastic products industry for the whole of 2022 was 77.716 million tons, a year-on-year decrease of 4.3%. Calcium carbonate is a basic raw material for the production of plastics, and its market has been affected to a certain extent.

According to the “China Calcium Carbonate Industry Market In-depth Research and Development Prospects Forecast Report 2023-2028” released by the Industrial Research Center, carbonate As an important chemical material, calcium has the advantages of good wear resistance and tear resistance, and relatively stable performance. It is widely used in many fields such as industry and food. Driven by downstream market demand, my country’s calcium carbonate production has gradually increased. In 2022, my country’s calcium carbonate output will be 36.845 million tons, a year-on-year increase of 3.9%. From the perspective of product segments, heavy calcium carbonate has become the largest segment of calcium carbonate, accounting for 61.2% of the total output; followed by light calcium carbonate, accounting for 38.8% of the total output.

Industry analysts said that at present, my country’s main calcium carbonate companies include Jinshan New Materials, Lude Chemical, Cologne Powder, and North China Calcium Industry, Changzhou Calcium Carbonate, Chenglong Calcium, Hongxing Calcium, Qintang Calcium, Gongga Xuexin, Hongri Calcium, Sanxing Calcium, Xintai Calcium, Cangshan Calcium, Guangyuan Chemical, Huanaxin Cai, Changxing Jinding, etc. Among them, companies such as Jinshan New Materials, Guangyuan Chemical, Warner New Materials, and Cologne Powder have relatively high market shares and have become leading companies in the industry.
