doi:10.3724/SP.J.1077.2007.01197

Abstract

Abstract: The sintering characters and phase composition of BaO-CeO₂-TiO₂ were examined with TG-DTA, SEM, EDAX and XRD. The pretreating temperature and sintering temperature were 900--1100℃ and 1250--1300℃,respectively. The results indicate that the samples Ba _6-3x Ce _8+2x Ti ₁₈ O₅₄(x=0.8) sintered at 1300℃ consist of A and B phases, whose elements molar ratio are Ce:O=1.0:1.3 and Ba:Ti:Ce: O=1.00:6.70:0.35:9.46 respectively. And the above sintered samples with permittivity of 28.72 have the highest quality factor of 4862.13GHz.
