Emerging high-tech industries continue to develop, and the market demand for electronic-grade hydrogen chloride gas is vast.

Hydrogen chloride is a colorless gas with a pungent odor with the chemical formula HCI. It has the characteristics of good thermal stability, easily soluble in water, soluble in various organic solvents such as ethanol, and does not burn in the air. It is widely used in industry and It is widely used in chemical industry, textile, metallurgy, electronics, medicine and other fields. Electronic-grade hydrogen chloride gas refers to high-purity hydrogen chloride gas with a purity higher than 99.999% used in the electronic field.

According to different sources of raw materials, the production process of electronic grade hydrogen chloride gas can be divided into generation method, hydrochloric acid removal method, synthesis method, etc. Among them, the generation method and the hydrochloric acid removal method are widely used electronic-grade hydrogen chloride gas production methods. The generation method refers to a method that uses concentrated sulfuric acid as raw material and reacts with salt to generate hydrogen chloride gas; the hydrochloric acid removal method refers to using concentrated hydrochloric acid as the raw material. Raw materials, a method of preparing hydrogen chloride gas through low-temperature drying, adsorption water removal, low-temperature distillation and other processes.

Electronic grade hydrogen chloride gas is mainly used in integrated circuits for pre-epitaxial silicon growth, passivation, high-temperature etching of gallium arsenide, vapor polishing, gettering and cleaning treatment, and removal of sodium ions. In recent years, against the background of the continuous rise of emerging high-tech industries such as domestic big data, Internet of Things, Internet of Vehicles, artificial intelligence, and 5G, the integrated circuit market has developed rapidly, and electronic-grade hydrogen chloride gas is an important raw material in its production process, and market demand has continued Increase.

In 2021, the scale of my country’s integrated circuit market has reached 176.8 billion U.S. dollars. Against this background, according to the“China Electronic Grade Hydrogen Chloride Gas Industry 2023-2027” released by the Industrial Research Center Market Monitoring and Future Development Prospects Research Report shows that the domestic market demand for electronic-grade hydrogen chloride gas will reach 8,115.2 tons in 2021, a year-on-year increase of 28.7%. In the future, under the background of the rising development trend of large-scale, high-integration and high-integrity integrated circuits, the domestic electronic-grade hydrogen chloride gas industry will continue to transform and upgrade in the direction of high-end, and the industry has broad room for development.

At present, my country’s electronic-grade hydrogen chloride gas still relies on imports. The domestic market is mainly dominated by foreign-funded enterprises such as Air Liquide of France, Merck of the United States, GFL of India, Linde of Germany, and Sumitomo Chemical of Japan; local enterprises mainly include Borui Electronic Technology , Weitai Fine Chemicals, Yanhe Chemicals, Donglong Technology, Jinhong Gases, etc. Affected by high technical barriers, the current electronic-grade hydrogen chloride gas products of local companies are still concentrated in the low-end market, and the degree of localization in the domestic market is low.

Industrial analysts personnel said that electronic grade hydrogen chloride gas is an important raw material in the production of integrated circuits. In recent years, in Against the background of the continuous emergence and development of domestic high-tech industries, the rapidly developing integrated circuit market has driven increasing demand for electronic-grade hydrogen chloride gas, and the industry has good development prospects. However, electronic-grade hydrogen chloride gas belongs to an industry with high technical barriers, and the level of localization in the domestic market is still relatively low. There is still huge room for growth in the industry in the future, and local companies need to increase technology research and development efforts.
