New electronic-grade carbon dioxide production capacity increases, and the industry is booming

Carbon dioxide, also known as carbonic acid gas, carbonic anhydride, and dry ice, is a compound composed of one carbon atom and two oxygen atoms. It is a colorless, odorless, non-combustible and non-flammable gas under normal pressure. Electronic grade carbon dioxide is a purified product of carbon dioxide, also known as high-purity carbon dioxide. my country promulgated the high-purity carbon dioxide GB/T 23938-2009 quality standard in September 2009. The purity (volume fraction) of CO2 in this standard is ≥99.999%.

As a high-end product in the field of carbon dioxide, electronic grade carbon dioxide has a wide range of applications, such as laser gas for laser cutting machines, electronic industry, reactor gas coolant, critical extraction in medicine, oxidation and diffusion in semiconductor manufacturing, chemical vapor deposition, Supercritical cleaning gas and other fields. In recent years, the development of national high-tech has opened up the application market of carbon dioxide, and the demand for electronic-grade carbon dioxide has gradually increased. However, due to limitations in purification technical conditions, the domestic supply of electronic-grade carbon dioxide mainly relies on domestic small-scale production devices and foreign imports, which has largely restricted the development of our country’s economy.

According to the “In-depth Research Report on the Global and China Electronic Grade Carbon Dioxide Industry in 2021” released by the Industrial Research Center, due to the electronic grade carbon dioxide industry It has high technical barriers. Before 2016, my country’s electronic grade carbon dioxide market demand relied on imports. Imported brands include Japan’s Showa and Taiwan’s Sanfu. Since 2016, my country’s electronics industry has developed rapidly, and the demand for domestic electronic-grade carbon dioxide is urgent, which has spawned many electronic-grade carbon dioxide, such as Jinhong Gas, Kemet Gas, Xinhua Yue Group, etc. However, the existing electronic-grade carbon dioxide production capacity still cannot meet the demand. With the growing domestic market demand, the industry has huge growth potential.

At present, the purification method of electronic-grade carbon dioxide mainly uses food-grade carbon dioxide as raw material. The purity of food-grade carbon dioxide is generally above 99.9%, with fewer impurities and lower CO and H2 contents. The use of new purification processes can effectively remove relevant substances in products. impurities; low raw material loss during the production process, energy balance and recycling in the new purification process, low power consumption, relatively simple and reliable process, high product yield, and low investment.

Industrial researchers believe that at present, the production capacity of several electronic-grade carbon dioxide companies in my country is generally around 1,000 tons. Compared with foreign countries, Enterprises, the production capacity of domestic enterprises is small, and the scale advantage is not obvious, resulting in the high cost of electronic grade carbon dioxide, which inhibits the development of the downstream industry of electronic grade carbon dioxide. In the future, with the continuous development of related industries such as laser cutting, electronics industry, reactor gas coolant, and medical critical extraction, the demand for electronic-grade carbon dioxide in downstream industries will continue to increase, prompting the high-prosperity development of the electronic-grade carbon dioxide industry.
