Abstract

Single-phased indium doped titanium dioxide (Ti1-xInxO2, x=0~5%) ceramics were synthesized by using solid-state reaction method in this study. The doping effect on the dielectric and impedance properties was investigated in a broad frequency range from 102 Hz to 106 Hz. The observed dielectric behavior can be ascribed to the Universal Dielectric Response. In higher frequency field, the dielectric permittivity varies slightly with the doping concentration x. However, the measured dielectric constant increases significantly with the increase of doping concentration within lower frequency range. The charged grain-boundary cores originated from the doping trivalent ion can be used to explain the results
