摘　　要：以BaCO3和TiO2为原料、Y2O3为添加剂制备了Y3+离子掺杂BaTiO3基电容器陶瓷试样。采用XRD和SEM技术分析了试样的物相和陶瓷的显微结构,测试了Y3+离子掺杂BaTiO3基电容器陶瓷系列试样的介电性能。结果表明,当Y3+离子掺杂浓度为0.3mol%时,在1310℃保温时间为2h时,可制备介电常数为13965.4,介质损耗为0.110的BaTiO3基电容器陶瓷材料。In this paper,the ceramics of BaTiO3 were prepared using BaCO3 and TiO2 as raw material,Y2O3 as doping agent.XRD and SEM are employed to analyze sample＇s phase and microscopic structure.The dielectric properties of BaTiO3 modified by Y3＋ ion doping were tested.Tests show that target substance with dielectric constant 13965.4 and dielectric loss 0.110 can be synthesized when concentration of Y3＋ is 0.3mol% and the system is heated at 1310℃ for 2h.
