Thread Content
Recently, the Hohhot Ecology and Environment Bureau in Inner Mongolia released a public announcement regarding the acceptance status of the environmental impact assessment documents for the Inner Mongolia Kemeite Electronic Materials project. The details of the project are as follows: Project name: Inner Mongolia Kemeite Electronic Materials Project； Construction unit: Inner Mongolia Kemeite Electronic Materials Co., Ltd ； Construction location: Tuoketuo Economic Development Zone, Hohhot City, Inner Mongolia Autonomous Region ； Project nature: New construction ； Investment amount: The total investment is 940 million yuan, of which 11 million yuan is allocated to environmental protection efforts, accounting for 1.17% of the total investment. Land area: The first phase of the project covers an area of 285.716 mu (19.05 hm2) ； Construction contents: This project will be constructed in two phases, and the evaluation covers Phase 1. The construction contents (from north to south within the plant area) mainly include an electrolyte preparation room, a gas cylinder warehouse, a filling station, electrolysis workshops No. 1–5, a distillation workshop, SF6 and CF4 purification workshops, SF6 and CF4 cleaning workshops, a power distribution area, office buildings, a cafeteria, and a substation. The total land area for the first phase is 285.716 mu, with a total construction area of 78,669 m². Upon completion, it will be capable of producing 12,000 tons per year of electron-grade high-purity sulfur hexafluoride and 2,500 tons per year of electron-grade high-purity carbon tetrafluoride, while also generating 6,500 tons per year of 40% hydrofluoric acid as a by-product.
Regarding Inner Mongolia Kemeite Electronic Materials Co., Ltd.: Inner Mongolia Kemeite Electronic Materials Technology Co., Ltd. was established on May 19, 2025, and is located at Room 308, Office Building of the Industrial Park Management Committee, Tuoketuo County, Hohhot City, Inner Mongolia Autonomous Region. It is a private joint-stock enterprise whose business scope includes the manufacturing of special electronic materials, the sales of such materials, as well as research and development in this field. It also provides technical services, develops new technologies, offers technical consultation, facilitates technical exchanges, carries out technology transfer, and promotes technological advancements. Sulfur hexafluoride is an excellent inert insulating gas, primarily used as a gas insulator in electronic devices, radar waveguides, particle acceleration systems, transformers, and lightning arresters. It is also employed as a refrigerant, in tracing applications, in medical fields, for etching processes in semiconductor manufacturing, and in underground cables. Carbon tetrafluoride is a plasma etching gas widely used for etching silicon, silica, silicon nitride, phosphosilicate glass, and tungsten thin film materials ； It is also widely used in applications such as surface cleaning of electronic devices, production of solar cells, laser technology, gas insulation, cryogenic refrigeration, leak detection agents, control of rocket attitude, and degreasing in printed circuit manufacturing. Due to its extremely high chemical stability, carbon tetrafluoride can also be utilized in metal smelting and the plastics industry. At the same time, carbon tetrafluoride has excellent oxygen-carrying capacity, and is widely used in ultra-deep diving experiments as a substitute for ordinary compressed air.
