B2O3掺杂对0.69CaTiO3-0.31LaAlO3微波介质陶瓷的性能影响
Effect of B2O3 Doping on the Properties of 0.69 CaTiO3-0.31LaAlO3 Microwave Dielectric Ceramics
摘要
Abstract
The effects of B2O3 additive on the sintering and microwave dielectric properties of 0.69CaTiO3-0.31LaAlO3 ceramics prepared by conventional solid-state route were investigated.The results of X-ray diffraction analysis showed that the addition of B2O3 does not change the crystal phase of ceramics.Moderate addition of B2O3 could not only effectively lower sintering temperature and promote the densification but also improve the dielectric properties.The 0.3wt% B2O3-doped 0.69CaTiO3-0.31LaAlO3 ceramic sintered at 1500 ℃ exhibits the optimal dielectric properties:εr ≈45.4,Qf ≈52800GHz,τf≈8.78 ppm/℃.关键词
