my country’s electronic-grade boron trichloride production capacity continues to grow, and import dependence is expected to decrease

Boron trichloride, with the chemical formula BCl3, appears as a colorless fuming liquid or gas, has a pungent sour smell, is toxic, and is a hazardous chemical. Boron trichloride is easily deliquescent and can be decomposed into hydrogen chloride and boric acid when exposed to water. It is soluble in alcohol and can be decomposed into hydrochloric acid and borate ester. It is soluble in some organic solvents such as benzene and carbon disulfide. Electronic-grade boron trichloride is high-purity boron trichloride used in the fields of semiconductors and integrated circuits, and its purity must reach above 99.999%.

Electronic grade boron trichloride is used in the electronics industry. It can be used in ion implantation, diffusion doping, dry etching and other processes in the manufacturing process of semiconductor silicon devices and integrated circuits. It can be used to treat aluminum, molybdenum disilicide, tungsten disilicide, Titanium-silicon alloy and other metals, metal compounds, and alloy materials are etched and are highly irreplaceable. The impurity content and purity of electronic-grade boron trichloride directly affects the performance indicators and yield of semiconductor devices and integrated circuits. Its purity is required to be above 5N level, and the production technical barriers are high.

The production of boron trichloride is in an inert gas environment, under certain temperature conditions, using boron powder and chlorine as raw materials to react to obtain a crude product, which is then distilled to obtain boron trichloride. Electronic grade boron trichloride is based on refined boron trichloride and is purified using adsorption, distillation and other processes to obtain the final product.

According to the “2021-2025 Electronic Grade Boron Trichloride Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center It shows that due to high technical barriers, before 2018, my country did not have the production capacity of electronic-grade boron trichloride, and market demand relied on imports, mainly from American Air Chemicals, American Praxair, British BOC Group and other companies. my country’s electronics industry is developing rapidly. Relying on imports of key raw materials is not only expensive and has long supply cycles. In the changing international political and economic situation, there are also risks in supply stability, which is not conducive to the development of my country’s electronics industry. Domestic electronic-grade trichloride Boron is in urgent need.

From 2018 to 2019, my country has successively constructed electronic-grade boron trichloride projects, such as Anhui Ipeco’s 100 tons/year production line, Cryogenic Energy’s 200 tons/year production line, and Taihe Gas’s 150 tons/year production line. Wire. In 2020, Shandong Yixin Environmental Protection’s 100 tons/year electronic grade boron trichloride project was approved as a key construction project in Shandong Province in 2020; in June 2021, Hebi Derui Technology’s annual output of 3,000 tons of electronic chemicals project entered the environmental impact assessment , its first-phase project includes 300 tons/year electronic-grade boron trichloride production capacity; Haining Yingdesai Electronics’ 1,000 tons/year electronic-grade boron trichloride production capacity is expected to be put into production in the second half of 2021.

Industry Analysts People said that the scale of my country’s electronic grade boron trichloride industry is constantly expanding, and production capacity is constantly expanding. If the products produced Stable quality that can meet the requirements of downstream customers will gradually be recognized by the market, and its share in the domestic market is expected to continue to increase. If the local electronic-grade boron trichloride production capacity currently built or under construction can continue to supply stably, my country’s import dependence on electronic-grade boron trichloride will continue to decline.
