Abstract

The 1 Miz dielectric constants of a variety of synthetic aluminate garnets: Y3Al5O12, Ho3A15O12, Y2.93Nd.07Sc2Al3O12 and Gd2.95Nd.05Sc1 98Cr .02A13O12 and several silicates: CaB2Si2O8 (danburite), Ca3Al2Si3O12 (grossular) and Mg2Al4Si5O18(cordierite) were determined using the two-terminal method with edge corrections. These data and polarizabilities derived from the published single crystal dielectric constants of simple oxides were used to compare compound polarizabilities obtained from the Clausius-Mosotti equation and the oxide additivity rule.
