摘要：

Monoclinic BiVO4 is formed by the hydrolysis of bismuth and vanadyl double alkoxide, followed by washing and drying. Its average particle size is almost-equal-to 45 nm. The chemical structure is described by the formula Bi(VO4). Sintered pellets with nearly theoretical density are prepared by hot pressing for 2 h at 750-degrees-C and 29.4 MPa. The electrical conductivity of the pellets has been measured at 150-degrees to 550-degrees-C. Data are interpreted in terms of ionic conductivity due to oxygen ion vacancies.
