Product Description
Carbon tetrafluoride, also known as tetrafluoromethane or CF4, is a chemical compound consisting of one carbon atom bonded to four fluorine atoms. It is a colorless, odorless gas that is classified as a perfluorocarbon (PFC). PFCs are known for their strong chemical stability and resistance to heat, electricity, and chemical reactions.
Here are some key properties and uses of carbon tetrafluoride:
- Chemical Formula: CF4
- Molecular Weight: 88.0043 grams per mole
- Melting Point: -183.6°C (-298.5°F)
- Boiling Point: -128.0°C (-198.4°F)
- Density: 3.72 grams per liter at 25°C (77°F)
- Solubility: Insoluble in water, but soluble in organic solvents.
Uses and Applications:
- Electrical Insulation: CF4 is commonly used as an electrical insulating gas in high-voltage equipment like transformers and capacitors due to its excellent dielectric properties.
- Plasma Etching: It is utilized in the semiconductor industry as a plasma etching gas to remove unwanted material from silicon wafers during the fabrication of microelectronic devices.
- Fluorine Source: CF4 is used as a source of fluorine in various chemical reactions, especially in the production of fluorocarbons and fluoropolymers.
- Fire Suppression: In some specialized applications, carbon tetrafluoride has been used as a fire suppressant due to its ability to displace oxygen and inhibit combustion.
- Tracer Gas: CF4 can be employed as a tracer gas in environmental studies and industrial leak detection due to its low reactivity and stability.
It is important to note that carbon tetrafluoride and other perfluorocarbons have been identified as potent greenhouse gases with a high global warming potential. Their long atmospheric lifetimes contribute to climate change. Efforts are being made to minimize their emissions and find more environmentally friendly alternatives.
