The production of boron trifluoride is difficult and the number of manufacturing enterprises in my country is small.

Boron trifluoride is an inorganic compound with the chemical formula BF3. It appears as a colorless gas, has a pungent odor, is toxic, corrosive, and suffocating. Boron trifluoride is soluble in cold water, soluble in some organic solvents, and is easily hydrolyzed. It can decompose into highly toxic fluoride smoke in humid air. When it comes in contact with water, it will react violently and decompose into fluoroboric acid and boric acid, which can corrode glass and can It corrodes a variety of metals and can react violently with organic matter. Boron trifluoride is a hazardous chemical.

The main preparation methods of boron trifluoride include: using diboron trioxide/borate and hydrogen fluoride as raw materials; using boron and fluorine as raw materials; using boron-carbon mixture and fluorine gas as raw materials; It is obtained by reacting a mixture of borax and fluorite as raw materials with concentrated sulfuric acid; using boric anhydride and potassium fluoroborate as raw materials and reacting with concentrated sulfuric acid; using sodium fluoroborate as raw materials and using thermal decomposition method.

Boron trifluoride can be used as semiconductor materials, rocket high-energy fuel, organic synthesis catalysts, boron isotope separation raw materials, chemical synthesis raw materials, metal alloy antioxidants, epoxy resin curing agents, etc. High-purity boron trifluoride can be used in the semiconductor industry in doping, ion implantation, oxidation diffusion, plasma etching, silicon/germanium epitaxial growth, etc. Doping is one of the important application fields of boron trifluoride. It is a commonly used boron doping product that can enhance the electrical properties of silicon wafers and is mainly used in the production of P-type semiconductors.

According to the “Boron Trifluoride Industry In-depth Market Research and Investment Strategy Suggestions Report 2021-2025” released by the Industrial Research Center, Research on boron trifluoride in my country began in the 1950s. Guangming Chemical Research and Design Institute was the first institution to research boron trifluoride, mainly researching boron trifluoride for high-energy fuels. With the rapid development and expansion of my country’s semiconductor industry, the demand for electronic-grade high-purity boron trifluoride in the Chinese market continues to rise. The technical barriers to the production of high-purity boron trifluoride are high, and the number of domestic production companies is small and the production capacity is small.

my country’s boron trifluoride manufacturers include: Runtai Chemical Nantong Co., Ltd. and Huagu Chemical Co., Ltd., which mainly produce boron trifluoride series complexes; Shandong Heyi Gas Co., Ltd., which can produce trifluoride Boron series complexes and high-purity boron trifluoride gas; Perma Pure Materials Co., Ltd. and Zhonghao Guangming Chemical Research and Design Institute Co., Ltd., these two companies can produce electronic grade boron trifluoride, but their production capacities are different. The production capacity is 0.5 tons/year and 1 ton/year. The production capacity is small and cannot meet the domestic market demand.

In addition to domestic companies, Japan’s Taiyo Nippon Sanso has also entered my country’s boron trifluoride industry layout. The electronic chemicals production line it built in Yangzhou includes boron trifluoride products. Industry analysts said that in general, the scale of my country’s boron trifluoride industry is relatively small, especially for electronic-grade boron trifluoride. Boron production capacity is weak, and demand mainly depends on imports. my country’s boron trifluoride industry has a large space for development in the future, but as a hazardous chemical, its production requires high technology and qualifications for companies, making it difficult for weaker companies to enter the market.
