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 and odorless gas at room temperature and atmospheric pressure. Here are some key points about carbon tetrafluoride gas:

1. Chemical Formula: CF4
2. Molecular Weight: 88.0 g/mol
3. Structure: Carbon tetrafluoride has a tetrahedral molecular geometry, with the carbon atom at the center and four fluorine atoms arranged around it.
4. Physical Properties: CF4 is a non-flammable gas. It is denser than air and has a high vapor pressure at room temperature.
5. Production: Carbon tetrafluoride can be produced by the reaction of carbon with fluorine gas or by the reaction of carbon tetrachloride with hydrogen fluoride. It is also a byproduct of certain industrial processes, such as aluminum production.
6. Chemical Reactivity: CF4 is a stable compound and is relatively unreactive under normal conditions. It is highly resistant to most chemical reagents, including strong acids and bases. However, it can react with strong reducing agents or alkali metals at elevated temperatures.
7. Applications: Carbon tetrafluoride has various industrial applications. It is commonly used as a plasma etchant in the semiconductor industry for the production of microchips and electronic devices. CF4 is also employed as a refrigerant in some specialized cooling systems and as a dielectric gas in high-voltage electrical equipment.
8. Environmental Impact: Carbon tetrafluoride is classified as a greenhouse gas and has a high global warming potential. Although it is not as prevalent in the atmosphere as other greenhouse gases, such as carbon dioxide or methane, it can contribute to climate change if released in significant quantities.
9. Safety Considerations: CF4 is not flammable and does not support combustion. However, it is important to handle it with caution, as it can displace oxygen and cause asphyxiation in high concentrations. Proper safety measures, such as adequate ventilation and monitoring, should be followed when working with carbon tetrafluoride gas.
10. Regulations: The use, handling, and release of carbon tetrafluoride are subject to regulations and guidelines, particularly due to its environmental impact as a greenhouse gas. Compliance with local regulations and best practices is essential to minimize its potential negative effects.
