Jul 15, 2019We also propose a model for CF3- production in CF4-SF6 gas mixtures that makes qualitative predictions, which are consistent with our measurements. Our studies show that a 20-3 CF4-SF6 mixture results in low thermal diffusion and a factor two enhancement of the fiducialization efficiency relative to that measured for pure SF6. Get Price

  • Carbon tetrafluoride - Wikipedia

    Tetrafluoromethane, also known as carbon tetrafluoride or R-14, is the simplest perfluorocarbon (C F 4).As its IUPAC name indicates, tetrafluoromethane is the perfluorinated counterpart to the hydrocarbon methane.It can also be classified as a haloalkane or halomethane.Tetrafluoromethane is a useful refrigerant but also a potent greenhouse gas. It has a very high bond strength due to theChemical formula: CF₄
