The market demand for carbon tetrafluoride (CF4) is increasingly strong, and the direct synthesis of fluorocarbon is its mainstream preparation method.

Carbon tetrafluoride (CF4), also known as tetrafluoromethane and perfluoromethane, is a colorless gas compound at normal temperature and pressure. Carbon tetrafluoride has the characteristics of good chemical stability, good oxygen solubility, non-flammability, and non-corrosiveness. It is soluble in chloroform and benzene, but insoluble in water. As a special electronic gas, carbon tetrafluoride is widely used in power systems, integrated circuits, solar cells, insulation materials and other fields.

There are four methods for preparing carbon tetrafluoride: direct synthesis of fluorocarbon, fluorination of chlorofluoromethane, fluorination of hydrofluoromethane, and direct fluorination of alkanes. The direct fluorination of alkanes is a traditional preparation method for carbon tetrafluoride. It has problems such as low yield of finished products and many by-products, and is gradually being replaced by emerging methods. The direct synthesis method of fluorocarbon has the advantages of high product purity, easy availability of raw materials, low production cost, and controllable reaction. It is suitable for large-scale production and is the mainstream preparation method of carbon tetrafluoride.

High-purity carbon tetrafluoride is a high-end product of carbon tetrafluoride, which refers to carbon tetrafluoride with a purity of more than 99.999%. It is widely used in fields such as phosphosilicate glass, silicon dioxide, and tungsten thin film material etching. In the early stages of industry development, my country’s high-purity carbon tetrafluoride was highly dependent on imports due to factors such as high technical barriers. In recent years, benefiting from the improvement of the technological maturity of local enterprises, the localization process of high-purity carbon tetrafluoride in my country has been accelerating, which provides favorable conditions for the development of the carbon tetrafluoride industry.

Carbon tetrafluoride has a wide range of applications. In power systems, carbon tetrafluoride is used as electrical arc extinguishing and insulating materials, and can be used to manufacture power switches, transformers and other power products. In the field of integrated circuits, carbon tetrafluoride can be used for ion etching. process, it is the most in demand plasma etching gas; in the field of solar cells, carbon tetrafluoride can be used to manufacture solar panels. In addition, carbon tetrafluoride also has broad application prospects in the chemical industry, with refrigerants, detergents, leakage detection agents, etc. as its end products. With the rapid development of downstream industries, my country’s carbon tetrafluoride market demand is increasingly strong. According to the “2023-2028 China Carbon Tetrafluoride (CF4) Industry Market In-depth Research and Development Prospects Forecast Report》shows that my country’s carbon tetrafluoride demand will reach 5,000 tons in 2022.

There are many carbon tetrafluoride production companies in my country, and the market competition is fierce. Chengdu Kemet, Guangdong Walter Gas, Guangxi Haohua Technology, etc. are my country’s leading carbon tetrafluoride companies. Among them, Kemet’s annual production capacity of carbon tetrafluoride has reached 1,200 tons, ranking first in my country.

Industry analysts said that as an electronic specialty gas, carbon tetrafluoride has excellent performance and is widely used in many fields. In recent years, with the continuous improvement of the technical level of local enterprises, my country’s carbon tetrafluoride production capacity has expanded rapidly and output has continued to grow. In terms of market competition, there are many carbon tetrafluoride production companies in my country and the market competition is fierce. It is expected that companies with high-purity carbon tetrafluoride production capabilities will occupy a larger share of the Chinese market in the future.
