High-purity carbon tetrafluoride (CF₄) gas supplied from China for semiconductor manufacturing, electronics, and specialty applications.
High-purity carbon tetrafluoride (CF₄ ) for semiconductor etching, cleaning processes, refrigeration, and plasma processing.
Carbon tetrafluoride is a colorless, non-flammable, and highly stable compressed gas. As one of the most stable organic compounds, it does not react with copper, nickel, tungsten, or molybdenum even at temperatures up to 900°C, and only slowly decomposes at carbon arc temperatures. CF₄ serves as a specialized etching and cleaning gas in semiconductor manufacturing, a component in refrigerant blends, and a dielectric gas for various electronics applications. It is also used in plasma processing and as a tracer gas. When exposed to high heat, container pressure increases, posing a risk of cracking and explosion, typically transported as a liquefied compressed gas.
