Dielectric constant and temperature
WebDielectric Constant. The dielectric constant of a substance is the ratio of the permittivity of the substance to the permittivity of the free space. It shows the extent to which a material can hold electric flux within it. Dielectric … WebThe temperature and pressure dependence of the dielectric constant of a number of cubic halides and oxides with a broad range of dielectric constants have been determined. For low-$\ensuremath{\epsilon}$ compounds the dielectric constant increases with increasing temperature, whereas for high-$\ensuremath{\epsilon}$ compounds the dielectric …
