| 摘 要： | 以BaCl2·2H2O、TiCl4和NdCl3为原料,采用水热法制备了掺钕的BaTiO3纳米粉体,并经高温烧结后得到瓷体。利用DTA、XRD、SEM等测试手段,分析了钕掺杂对钛酸钡粉体及其陶瓷电性能的影响。研究表明,掺杂后,钕固溶到了钛酸钡的晶格中并取代钡位或钛位。钕的掺杂有助于获得细晶高致密的陶瓷,当W(NdCl3)%为0.6时,致密度最高,常温下相对介电常数高达5650,击穿场强达到3.5kV/mm。

| Abstract: | Superfine Nd-doped barium titanate powder was prepared by hydrothermal method.The effect of doping Nd in powder and ceramic electric properties were discussed through DTA,XRD and SEM. As indicated by results,Nd could substitute Ba or Ti,which was helpful to get the microstructure with tiny grain and high density.When W(NdCl3)% was 0.6,the density reached the maximum and dielectric constant reached 5650,destroyed electric strength rose up to more than 3.5kV/mm. |
