The dielectric behavior of some fluorogases and their mixtures

IN THE last 15 years the practical possibilities of the fluorogases as dielectrics have increased and their use has been demonstrated in several applications.1,2 Sulfur hexafluoride and Freon 12 are available economically in large quantities and for this reason have received extensive studies.3,4,5 However, fragmentary data showed that many compounds, although not yet available in large quantities, held promise and needed comprehensive evaluations.
