Tetrafluoromethane (CF4, also known as Carbon Tetrafluoride) is a color- and odorless gas which is neither flammable nor toxic. It is shipped as a liquid under pressure. It may be narcotic at high concentrations. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. CF4 Gas Uses- Refrigerant. Semiconductor. NDIR Sensors. Propellants. Neutron detectors. It is used as a low temperature refrigerant and also as a plasma etchant in electronics fabrication. The main industrial emissions of CF4 are as a by-product of smelting aluminium. As a fluorinated hydrocarbon, it absorbs strongly in the infrared and can be detected with NDIR sensors.
