Some dielectric properties of solid glycerine

Abstract

At high frequency, obtained by resonance, Thwing gives 56·2 for the specific inductive capacity of glycerine at 15° C. The specific inductive capacity of pure liquid glycerine at 8° C. was found to be about 60, whether the frequency of experiment was of the order 2 million or 100. At a frequency of 120 the specific capacity of glycerine varies from about 60 to 4·6, as the temperature is varied from - 50° to - 100° in platinum degrees. The present paper deals with the specific capacity of glycerine at temperatures varying from about + 10° to - 80° C. The methods of experiment and the apparatus are those described in connection with the earlier experiments.
