摘要
通过XRD衍射仪、SEM扫描电镜表征掺杂ZnO-B_2O_3-Li_2O_3(ZBL)低软化点玻璃助烧剂的Ca_(0.6)La_(0.8/3)TiO_3-Li_(0.5)Nd_(0.5)TiO_3(CLLNT)陶瓷样品的物相组成及结构,研究ZBL玻璃的掺杂量对CLLNT样品烧结性能及微波介电性能的影响。研究表明:加入助烧剂(ZBL)后,CLLNT陶瓷的烧结温度降低至950℃;添加9 wt%ZBL玻璃的CLLNT陶瓷在950℃烧结3h,能够获得较好的介电性能:ε_r=82,tanδ=0.0026,τ_f=16 ppm/℃(1 MHz)。
The phase composition and structure of low softening point sintering aid doped ZnO-B_2O_3-Li_2O_3（ZBL）Ca_0.6La_0.8/3TiO_3-Li_0.5Nd_0.5TiO_3（CLLNT） ceramic samples were characterized by XRD and SEM.The effects of doping content of the compound sintering aids of ZBL glass on the phase structures and microwave dielectric properties of CLLNT ceramics were investigated.The result showed that after adding the ZnO-B_2O_3-Li_2O_3 glass,the sintering temperature of the CLLNT ceramic had been efficiently lowered to 950 °C.When the addition amount of ZBL glass was9wt%,CLLNT ceramics sintered at 950 °C for 3h had excellent properties：dielectric constant ε_r=82,tanδ =0.0026,τ_f=16ppm/°C（1 MHz）.
