Carbon tetrafluoride--CF4
Tetrafluoro methane, also known as carbon tetrafluoride, is the simplest fluorocarbon (CF4). It has a very high bond strength due to the nature of the carbon-fluorine bond. It can also be classified as a haloalkane or halomethane.

The major use of carbon tetrafluoride is in refrigerators as refrigerants and is a major greenhouse gas too.
Here we will study the uses and applications of Carbon tetrafluoride in various areas and industries. This article will unfold its utility.
Refrigerant
* Carbon tetrafluoride CF4 is mainly used as a low temperature refrigerant and gas insulator.
* CF4 is preferred more due to its inert and non-flammable characteristics.
Semiconductors
* CF4 is used in semiconductor as silicon wafers in plasma etching.
* CF4 is used as photovoltaic agent.
* Carbon Tetrafluoride (CF4) has its application as semiconductor chamber cleaning, etching applications, and in Flat Panel Display etching.
Propellants
* CF4 is used to manufacture propellants and other industrial chemicals.
* CF4 is used in aerosol spray cans as a propellant, as it can be easily compressed into a liquid.
NDIR sensors
* CF4 being a fluorinated Hydrocarbon gets stronger absorbed in infrared and gets detected by NDIR sensors.
* NDIR sensors are used for measuring greenhouse gas concentrations .CF4 being a potent source gets easily detected and used widely.
Neutron detectors
* CF4 plays a key role in neutron detectors.
* CF4 combined with helium-3 gas has its use in neutron detectors which work by effectively stopping proton and tritium.
* Like most hydrofluorocarbons , CF4 contribute to greenhouse gas.
* CF4 does has major contributions in global warming and effect on ozone layer.
Conclusion
Carbon tetrafluoride is an important industrial chemical. It can also be used such as refrigerant liquid, as dielectric material and as propellant in aerosols, but it is also the starting material in the synthesis of the highly valuable tetraflu-oroethylene by the process described in U.
FAQ
Q1. What's the MOQ?
A:Different products have different MOQ,Pls feel free to contact with me directly for your requirement.
Q2:What is the delievery time?
A:Depends on your quantity.Normally it will cost 7-10 days for preparation.
Q3:What is the package, storage& transportation details?
A:Package:Steamless steel cylinder with different valves,or as to your requirement.
Stored in shady, cool, dry, eventilated warehouse, and keep away from sunlight and any ramming.
Q4:What is the payment terms?
A:30% T/T in advance, balance against the B/L.
Q5:How to check gas quality?
A: Before filling the gas, the cylinder will be treated carefully, such as cleaning, drying, vacuum pumping and replscement.
Then, we will take tests every treated cylinder to assure them inside purity.
Thirdly, we will take a test for all the gas after fill into the cylinder, to make sure the quality of the gas along with the tested reported.
Q6: If the cylinder recycled and can be refilled gas again?
A: Yes, usually the seamless steel cylinder can recycle to use for 20 years, and also can be refill gas again.
But , when you ordered our cylinder, you have to inform us before exporting, we will handle all the import customs clearance formalities.
