Lu C.-H.Mizutani N.2019-05-132019-05-13199408842914https://scholars.lib.ntu.edu.tw/handle/123456789/407510Pyrochlore-type Pb2FeW06.5 is difficult to be sintered without applied pressure at temperatures lower than its decomposition temperature. Through hot pressing or hot isostatic pressing processes, densification of specimens is greatly enhanced; moreover, grain growth during sintering is effectively suppressed. Densified Pb2FeWO<55 exhibits paraelectric characteristic from ¡X135¢X to ¡X 2 ¢XC with low dielectric constants and low dissipation factors. The dielectric constants show rather weak dependence of temperature and frequency. ? 1994, Materials Research Society.
