| 摘 要： | 用Ｃｏ、Ｎｂ、Ｙ元素对ＺｎＯ材料进行掺杂制备出ＺｎＯ基导电陶瓷样品。研究了掺杂含量及掺杂方式对ＺｎＯ基导电陶瓷电阻率的影响。用溶胶一凝胶法制得Ｙ（ＮＯ３）３含Ｔｉ掺杂剂溶胶且与Ｙ２Ｏ３固相氧化物掺杂进行了比较。结果表明，Ｙ（ＮＯ３）３含Ｔｉ溶胶掺杂可制备出室温电阻率很低的ＺｎＯ基导电陶瓷，其室温电阻率可达３．３８ｘ１０－２Ω·ｍ，溶胶引入量为０．０５％ｍｏｌ。

| Abstract: | The samples of ZnO-based conductive ceramics have been prepared by doping ZnO materialswith Co, Nb and Y elements. Influence of doping amount and method on the resistivity of ZnO-basedconductive ceramics is investigated. Y(NO3)3 sol dopants with Ti are fabricated by a sol-gel processand compared with Y2O3 solid phase additives, the results show that ZnO-based conductive ceramicsof very low resistivity at room temperature can be prepared by use of Y(NO3)3 sol dopants with Ti,the resistivity is as low as 3.38 x 10--2n m and the amount of Y(NO3)3 sol dopants with Ti is 0.05%mol. |
