Abstract
Cerium(III) orthovanadate with a small deviation from stoichiometric c omposition is a p-type semiconductor between 30 and 800 degrees C. The electrical conduction in cerium(III) orthovanadate is due to thermall y activated hopping of holes on equivalent Ce3+-Ce4+ lattice sites. Th e DTA result of CeVO4 indicated a possible phase transition at about 7 0 degrees C. The IR spectrum of the sample showed bands at 865 and 810 cm(-1), typical of VO4 group of orthovanadates.
