| 摘 要： | 在1 270℃的烧结温度下,采用固相反应法对BaTiO3粉体进行Nd2O3和ZrO2双施主复合掺杂,合成(Ba0.98Nd0.02)(Ti1–xZrx)O3(BTNZ)陶瓷,研究了Zr掺杂量对BTNZ陶瓷的显微结构及介电性能的影响。结果表明:随着Zr掺杂量的增加,BTNZ陶瓷的介电峰移向室温;加入适量的Zr离子替代BaTiO3中的Ti离子能很好地改善BTNZ陶瓷的介电性能,当Zr掺杂量为x=0.01时,BTNZ陶瓷的相对介电常数可达7 200。

| Abstract: | (Ba0.98Nd0.02)(Ti1-xZrx)O3(BTNZ) ceramics were prepared using solid phase synthesis method at the sintering temperature of 1 270 ℃.The effects of Zr-doping amount on microstructure and dielectric properties of the ceramic were investigated.The results show that the dielectric peak moves to the room temperature with the increase of Zr dopant,that Zr4+ replace the Ti4+ of BaTiO3 improve the dielectric properties of the BTNZ ceramics,and when the amount of Zr4+ doping is x=0.01,the r is 7 200. |
