Refrigerant 14 (Tetrafluoromethane)

CAS №: 75-73-0

EC №: 200-896-5

Synonyms: Tetrafluoromethane (R14), Carbon fluoride; Freon 14; Perfluoromethane; Carbon tetrafluoride; Halocarbon 14; R 14; PFC 14;

Molecular formula: CF4

Tetrafluoromethane, also known as carbon tetrafluoride, is the simplest fluorocarbon (CF4). Halon 14 has very high bond strength due to the nature of the carbon–fluorine bond.


Tetrafluoromethane is used:

• as a low temperature refrigerant;

• in electronics microfabrication alone or in combination with oxygen as a plasma etchant for silicon, silicon dioxide, and silicon nitride;

• in high-voltage equipment production;

• in neutron detectors.

Depending on the concentration, Refrigerant 14 inhalation can cause headaches, nausea, dizziness and damage to the cardiovascular system (mainly the heart). Long-term exposure can cause severe heart damage. Due to its density, tetrafluoromethane can displace air, creating an asphyxiation hazard in inadequately ventilated areas. But R-14 is a non-flammable and low toxic gas at normal temperature.
