The present work attempts to investigate the sintering characteristics, grain boundary morphology and electric conductivity of Nb2O5 doped TiO2 semiconductor ceramics. X-ray diffraction results showed evidence of a second phase beside the rutile TiO2 when Nb2O5 exceeds 0.7mol%. SEM images showed tha...
