Product Description
Carbon tetrafluoride, also known as tetrafluoromethane or CF4, is a colorless and odorless gas. It is composed of a carbon atom bonded to four fluorine atoms. The molecular formula for carbon tetrafluoride is CF4.
Properties of Carbon Tetrafluoride (CF4):
- Molecular Formula: CF4
- Molecular Weight: 88.0043 g/mol
- Density: 3.72 g/L (at 25°C and 1 atm)
- Melting Point: -183.6°C
- Boiling Point: -127.8°C
- Solubility: Insoluble in water
- Chemical Structure: C(F)4
Carbon tetrafluoride is a non-flammable gas under normal conditions and is not reactive with most common materials, including metals, plastics, and rubber. It has a high dielectric strength, which makes it useful in electrical applications. CF4 is also known for its excellent thermal stability and low toxicity.
Applications of Carbon Tetrafluoride:
- Electronics Manufacturing: Carbon tetrafluoride is commonly used as an etchant gas in the semiconductor industry for plasma etching of silicon dioxide and silicon nitride layers. It is also used in the manufacturing of flat panel displays, integrated circuits, and microelectromechanical systems (MEMS).
- Fire Extinguishing: CF4 is used in some fire suppression systems as an inert gas. It can displace oxygen and suppress the combustion process, making it effective in extinguishing fires in enclosed spaces.
- Fluorine Source: Carbon tetrafluoride is a precursor for the production of various fluorine compounds, including Teflon (polytetrafluoroethylene) and other fluoropolymers.
- Electrical Insulation: Due to its high dielectric strength, CF4 is used as an insulating gas in the electronics industry, especially in high-voltage equipment like transformers and capacitors.
- Tracer Gas: CF4 is sometimes used as a tracer gas in laboratory experiments and industrial processes to determine airflow patterns, detect leaks, and measure ventilation efficiency.
It's worth mentioning that carbon tetrafluoride is a potent greenhouse gas, contributing to the depletion of the ozone layer and global warming. Its release into the atmosphere should be minimized to reduce its environmental impact.
