Characteristics of Carbon Tetrafluoride (CF4):
Chemical Formula: CF₄
Appearance: Colorless gas.
Boiling Point: -128.1°C (145 K; -198.6°F)
Melting Point: -219.7°C (53.4 K; -363.5°F)
Density: 3.49 g/L at 0°C (32°F) and 1 atm.
Vapor Pressure: 1013 kPa at 25°C (77°F)
Ozone Depletion Potential (ODP): 0 (does not contribute to ozone depletion).
Global Warming Potential (GWP): 7,390 over a 100-year time horizon (highly potent greenhouse gas).
Uses: Used as an etchant in semiconductor manufacturing, a plasma source gas for plasma-enhanced chemical vapor deposition (PECVD), a fire extinguishing agent, and as a tracer gas in leak detection. It has also been used historically as a refrigerant and aerosol propellant.
Safety Information:
Non-flammable but can displace oxygen in confined spaces leading to asphyxiation.
Exposure to very cold liquid can cause frostbite if it comes into direct contact with skin.
Inhalation of high concentrations can cause respiratory distress.
