摘要：

Perovskite lead indium niobate free of pyrochlore phase has been synthesized by a novel calcination process. The process is described, and the dielectric constant and pyroelectric coefficient of the ceramic body have been determined as a function of temperature. X-ray diffraction investigation shows no obvious indium/niobium atom ordering at the B-site on isothermal annealing. This lack of extended ordering is in part manifested by the diffuse phase transition behavior of the dielectric constant and of the spontaneous polarization of virgin as well as annealed lead indium niobate ceramics. © 1991, Taylor & Francis Group, LLC.
