Product Description
Carbon tetrafluoride, also known as tetrafluoromethane or CF4, is a colorless, odorless gas composed of one carbon atom bonded to four fluorine atoms. It is a member of the group of compounds known as halocarbons, which contain carbon-halogen bonds.
Properties of Carbon Tetrafluoride (CF4):
- Chemical formula: CF4
- Molecular weight: 88.0043 g/mol
- Melting point: -183.6 °C (-298.5 °F)
- Boiling point: -128 °C (-198 °F)
- Density: 3.72 g/L (at 0 °C and 1 atm pressure)
- Solubility: Insoluble in water, but slightly soluble in organic solvents such as ethanol and acetone
- Molecular geometry: Tetrahedral
Carbon tetrafluoride is a highly stable compound due to the strong carbon-fluorine bonds, which makes it non-flammable. It is also chemically inert under normal conditions, meaning it does not readily react with other substances. CF4 is not toxic, but it can displace oxygen in high concentrations, leading to asphyxiation if inhaled in excessive amounts.
Applications of Carbon Tetrafluoride:
-
Electronics industry: CF4 is commonly used in the semiconductor industry as a plasma etchant during the fabrication of integrated circuits. It selectively removes layers of silicon dioxide (SiO2) or silicon nitride (Si3N4) from silicon wafers.
-
Medical applications: Carbon tetrafluoride has medical applications, including its use as a contrast agent in medical imaging techniques like positron emission tomography (PET). It can also be used in the synthesis of pharmaceutical compounds.
-
Fire extinguishing: CF4 is used in some specialized fire extinguishing systems, particularly in situations where water or other extinguishing agents may be ineffective, such as electrical fires or fires involving reactive metals.
-
Insulating gas: Due to its high dielectric strength, carbon tetrafluoride is used as an insulating gas in high-voltage electrical equipment, such as circuit breakers and switchgear.
It's important to note that CF4 is a potent greenhouse gas with a high global warming potential. Its release into the atmosphere contributes to climate change. Therefore, its usage and emissions are regulated in many countries to mitigate its environmental impact.
