The pressure increase ratio of the self‐decomposition of tetrafluoroethylene to carbon and tetrafluoromethane can be computed with sufficient accuracy via thermodynamic standard procedures by using the ideal gas law. Thermodynamic analysis with regard to real gases showed that the deviations are largely self‐compensating and therefore negligible in the pressure and temperature range of technical interest. The increase ratio is independent of the pressure and significantly dependent on the initial temperature. The flame temperature is about 2650 K like with stoichiometric H 2 /O 2 mixtures. The computations were extended to various gaseous TFE mixtures of technical interest.
