Dielectric constants conductive liquids, data table

The dielectric constant and thermal conductivity decrease with increasing temperature, whereas the specific heat increases. The thermal conductivities, cubic expansion coefficients, dielectric constants, and electrical conductivities of various solvents are listed in Table 11. Critical data of solvents and the technical use of supercritical liquids are described in [14.82]. 

In Section 3.8 about dispersions, the use of permittivity or conductivity parameters was discussed. From Section 2.3.4, we know that conductivity is dependent on the density of charge carriers and their mobility. In the frequency range less than 10 MHz, tissue admittance is usually dominated by the conductivity of the body electroljrtes, but at higher frequencies it is dominated by the dielectric constant. The electroljrtes without cells, in particular urine and cerebrospinal fluid (CSF), have the highest low-frequency conductivity thus, the higher the cell concentration, the lower the low-frequency conductivity. Tooth, cartilage and bone, lipids, fat, membranes such as the skin stratum comeum (SC), and connective tissue may contain many inorganic materials with low conductivity, but they are very dependent on body liquid perfusion. Tissue conductivity data are tabulated in Table 4.2.
