摘要
利用传统的固相法制备BaO-Sm2O3-TiO2系陶瓷。通过复合添加氧化物ZnO、CuO和玻璃料Bi2O3-B2O3-ZnO-SiO2(BBZS),系统的烧结温度降至900℃。研究了玻璃料的添加量对介电性能的影响。按BaSm2Ti4O12+1%(质量分数)ZnO+1%(质量分数)CuO+x%(质量分数)BBZS(0<x≤30)配方,当x=25,预烧温度为1100℃和烧结温度为900℃时,有以下的微波特性:εr=60.51,Qf=2256GHz,τf=15.02×10^-6/℃,该陶瓷材料有望与纯Ag电极共烧,应用到LTCC领域。
BaO-Sm2O3-TiO2 microwave dielectric ceramics were prepared by traditional solid sate reaction technique. By adding a proper amount of ZnO, CuO and BiEOa-BEOa-ZnO-SiOE(BBZS) glass, the sintering temperature of the system was successfully lowed to 900℃ .The effect of the amount of the glass on the dielectric properties was investigated. The composition is BaSm2Ti4O12+1 wt% ZnO+ lwt%CuO+xwt% BBZS(0〈x≤30). The ceramic of BaSm2Ti4O12- lwt%ZnO+ 1wt%CuO+25wt%BBZS calcined at 1100℃ and sintered at 900℃ has the following microwave characteristics: εr= 60.51, Qf= 2256GHz, Tf = 15.02 × 10^-6/℃. the ceramics is promised sinterd with Ag electrode and' is a promising candidate material for LTCC applications.
