Product Description
Carbon tetrafluoride, also known as tetrafluoromethane or CF4, is a colorless and odorless gas. It belongs to the group of compounds known as halogenated hydrocarbons, where all hydrogen atoms in a hydrocarbon molecule are replaced by halogen atoms. In the case of CF4, all four hydrogen atoms in methane (CH4) are replaced by fluorine atoms (F).
Here are some key points about carbon tetrafluoride:
Chemical formula: CF4
Molar mass: 88.0043 g/mol
Melting point: -183.6°C (-298.5°F)
Boiling point: -128.0°C (-198.4°F)
Density: 3.722 g/L (at 25°C and 1 atm)
Solubility: CF4 is sparingly soluble in water.
Properties and Uses:
- Inert gas: CF4 is an inert gas, meaning it is non-reactive under normal conditions. It is stable and does not readily participate in chemical reactions.
- Electrical insulation: CF4 has excellent electrical insulating properties, which makes it useful in various electrical applications, such as in gas-insulated electrical equipment.
- Plasma etching: CF4 is commonly used in the semiconductor industry as a plasma etching gas. It is used to remove layers of material during the fabrication of microchips and other electronic devices.
- Refrigerant: CF4 has been used as a refrigerant in some specialized applications, although its use as a refrigerant has been significantly reduced due to its high global warming potential.
- Fire extinguishing: In certain situations, CF4 can be used as a fire extinguishing agent for electrical fires. It can displace oxygen and thus suppress the combustion process.
- Greenhouse gas: CF4 is classified as a potent greenhouse gas, contributing to global warming. As a result, its emissions are regulated to reduce its impact on the environment.
It's important to handle CF4 with caution due to its potential hazards. Inhalation of high concentrations can cause asphyxiation since it can displace oxygen. Additionally, CF4 is an ozone-depleting substance and has a high global warming potential, so its release into the atmosphere should be minimized.
