Abstract

The dielectric constants (K) have been measured near ambient temperature for polycrystalline bulk ceramics of the crystallographic shear compounds TiNb₂₄O₆₂, Ti₂Nb₁₀O₂₉, and TiNb₂O₇. These show enhanced K's over Nb₂O₅ and TiO₂, with the 2:10:29 phase displaying an ambient temperature K of approximately 130. We also report the effects of partial substitution of Nb by Ta. In general, the dielectric constants are enhanced for 5-10% Ta substitution, with the detailed behavior differing for the three phases.
