Effects of Doping ZnO-2B2O3-7SiO2 Glass by Sol-gel Method on BaO-Sm2O3-4TiO2 Ceramics
BaO-Sm2O3-4TiO2 (abbreviated BST) ceramic powder was prepared by the conventional solid-state reaction method. The effects of doping ZnO-2B2O3-7SiO2 (abbreviated ZBS) glass by sol-gel method on the sintering behaviors, microstructure, phase composition and dielectric properties of BST ceramics were investigated. The experimental results reveal that the main phase of samples doped with ZBS glass is tungsten bronze structure type BaSm2Ti4O12 phase, a litter Sm2Ti2O7 phase is also observed. The sintering temperature of BST ceramics is remarkably reduced from 1350°C to 1050°C and the good dielectric properties of εr=60.2, tan6=0.004, τf=-7.9ppm/°C were obtained for BST ceramics doped with 6wt％ ZBS glass by sol-gel method sintered at 1050°C for 3h.
