    Abstract

    A holder for dielectric specimens is described which can be used over a temperature range from room temperature to 500 C and over a frequency range from 102 to 107 cps. Provision is made for measuring the thermal expansion of the sample. The dielectric constant can be determined with a probable error not exceeding about 1 per cent and the dissipation factor with a probable error not exceeding about 0.0001 or 5 per cent, whichever is greater, for the lower frequencies and about 0.0015 or 5 per cent, whichever is greater, at 10 mc per sec. Illustrative data on boron nitride and alumina body are given.
