摘要
本文对（Zn0.65Mg0.35）TiO3-CaTiO3（ZMT-CT）系统的微观结构和介电性能进行了研究。研究结果表明,通过添加一定量H3BO3-ZnO-BaCO3（BZB）玻璃能够促进晶粒生长,有效降低烧结温度。同时,调节（Zn0.65Mg0.35）TiO3和CaTiO3比例可以获得温度系数在零附近的瓷料。当加入6.5wt%BZB时瓷料可以在900℃烧结,rε=21~22,αε（±30 ppm/℃,tanδ=1.3×10-4（1 MHz）,是制备LTCC（低温共烧陶瓷电容器）的优秀候选材料,具有很好的应用前景。
The microstructure and dielectric properties of（Zn0.65Mg0.35）TiO3-CaTiO3（ZMT-CT） system were investigated.The results reveal that doping of H3BO3-ZnO-BaCO3（BZB） in modest amount can improve the crystal grain growth of ZMT-CT and obtain good dielectric properties.Due to the compensating effect of CaTiO3（CT）,the temperature coefficient of dielectric constant for ZMT could be adjusted to around zero value.Typically,the optimal dielectric properties of εr=21-22,αε±30 ppm/ ℃,tan δ1.3×10-4 could be obtained for the 6.5wt%BZB-doped sample sintered at 900 ℃,which can be provided as suitable candidates for LTTC and have a promising practicality prosperity.
