添加B2 O3对0.7CaTiO3-0.3 NdAlO3陶瓷烧结及其介电性能的影响
Effect of Adding B2 O3 into 0.7CaTiO3-0.3 NdAlO3 Ceramics on its Sintering and Performance
摘要
Abstract
0.7CaTiO3-0.3NdAlO3 (CTNA30)ceramics is a kind of widely used microwave dielectric ce-ramics with high sintering temperature.In this article,various contents of B2 O3 were introduced into CT-NA 30 to decrease its sintering temperature.Then,the influences of B2 O3 content on the sintering temper-ature,morphology,microstructure and microwave dielectric properties of CTNA30 were investigated with x-ray diffract meter (XRD),environmental scanning electron microscope (ESEM)and vector network ana-lyzer.The results showed that ceramics could be sintered more easily when doped with B2 O3 .Moreover, the sintering temperature could be decreased to 1 300 ℃ from 1 500 ℃ when doped with 2wt% B2 O3 and the correspondingεr reached the maximum 49.99,Qf about 57 862 GHz,which decreased with the increase of doping level,andτf was about 5.39×10-6∕℃.关键词
