Carbon Tetrafluoride, represented by the chemical formula CF4 (molecular weight: 88.004 g/mol), is the simplest fluorocarbon (tetrafluoromethane). It belongs to the haloalkane family and consists of a single carbon atom covalently bonded to four fluorine atoms in a symmetrical tetrahedral spatial orientation (sp3 hybridization). Because of the extreme electronegativity of fluorine and the high energy of the C-F bond (~485 kJ/mol), CF4 exhibits outstanding thermal, chemical, and physical stability.
Under ambient conditions, Carbon Tetrafluoride is a colorless, odorless, non-flammable gas. Unlike other halogenated hydrocarbons, it does not decompose under moderate heat and shows exceptional resistance to acids, bases, and oxidizing agents. In semiconductor manufacturing, this structural inertness is essential, allowing the gas to safely traverse mass flow controllers before undergoing ionization in plasma chambers.

Analyzing key market drivers, semiconductor integration, and environmental mitigation initiatives.
Electronic-grade CF4 (purity ≥99.999% or 5N/6N) is critical for dry etching thin films like silicon dioxide (SiO2) and silicon nitride (Si3N4). The plasma-activated fluorine radicals clean residues without degrading underlying layers.
In Plasma-Enhanced Chemical Vapor Deposition (PECVD) setups, CF4 is blended with oxygen to remove silicon-based build-ups, keeping chamber walls clean while reducing downtime.
Thanks to its extremely low boiling point of -128.1 °C, CF4 is used as a component in mixed-gas cryogenic systems. It is key for deep-space cooling, scientific freezers, and specialized medical logistics.
While CF4 has zero ozone depletion potential, it features a high Global Warming Potential (GWP) of approximately 7,390 and an atmospheric lifetime of 50,000 years. Modern factories integrate point-of-use (POU) abatement systems, such as thermal decomposition or catalytic reactors, to destroy over 99% of unreacted CF4 in effluent streams. YANXA supports green industrial initiatives by helping clients optimize process parameters to minimize gas consumption.
How automation, geographical raw material access, and advanced analytics ensure consistent supply.
Our manufacturing partners in China employ Factory 4.0 principles, utilizing distributed control systems (DCS) to monitor the synthesis and purification of fluorocarbons. By using crude fluorination systems combined with cryogenic fractional distillation columns, we reduce trace impurities like moisture, oxygen, nitrogen, and carbon monoxide to parts-per-billion (ppb) levels.
China holds a natural geographic advantage with abundant fluorspar (CaF2) deposits, the raw material source for hydrofluoric acid. This vertical integration buffers the supply chain from raw material volatility. YANXA leverages this stable chemical source to offer reliable pricing and steady delivery timelines, even during periods of global supply strain.
All CF4 orders are shipped in specialized high-pressure steel or aluminum alloy cylinders, prepared and tested under strict ISO 9001:2008 and DOT specifications. This ensures maximum safety and purity from the production line to the cleanroom floor.
Analyzing how CF4 and our broader portfolio serve demanding engineering sectors.
In TFT-LCD and OLED production, CF4 is used for etching the passivating oxide layer and removing contaminants on indium tin oxide (ITO) electrodes, ensuring high-quality pixels and reliable display performance.
CF4 plays a key role in plasma-treating polymer surfaces. By introducing fluorine groups, it increases surface energy, hydrophobic properties, and chemical resistance without altering the bulk mechanical properties of the material.
As a fluorinated gas source, CF4 acts as a reactive gas in advanced metallurgy, helping passivate or modify the surface layer of fine metal powders, such as spherical aluminum-magnesium alloys.
