中文摘要	采用固相法,研究了Nd2O3掺杂量对ZBS玻璃添加的Ba0.65Sr0.35TiO3(BST)基低温烧结的陶瓷的物相组成、显微结构及介电性能的影响。结果表明:Nd2O3的掺杂并没有改变低温烧结的BST基陶瓷的物相结构,仍为单一钙钛矿结构。随着Nd2O3掺杂量的增大,BST基陶瓷的介电常数先增大然后减小,介质损耗先减小然后增大。当Nd2O3添加质量分数为1.5%,烧结温度为975℃时,BST基陶瓷的综合性能较好,此时相对介电常数为667,介质损耗为0.01,在–30~+85℃容温变化率为–35.2%~14.8%。; The influence of Nd2O3 doping amount on material phase, microstructure and the dielectric properties of Ba0.65Sr0.35TiO3(BST) series low temperature sintering ceramics doped with ZBS glass were investigated by the traditional solid state process. The results show that the main crystal phase of BST ceramics doped with Nd2O3 has a perovskite structure and has not the obviously secondary phase. When Nd2O3 doping amount increases, the dielectric constant of BST ceramics increases firstly and then decreases and the dielectric loss decreases firstly and then increases. The dielectric properties of BST ceramics doped with ZBS glass and with mass fraction of 1.5% of Nd2O3 and sintered at 975 ℃ are good:relative permittivity of 667, dielectric loss of 0.01,the change rate of capacitance is –35.2%-14.8% in the range of –30–+85℃.
