| 摘 要： | 目的以纳米CuO作为烧结助剂制备(Ba0.87Ca0.09Sr0.04)(Ti0.90Zr0.04Sn0.06)O3陶瓷(BC-STZS),研究纳米CuO的用量及烧结温度对BCSTZS陶瓷的微观形貌以及介电性能的影响,以期获得低烧Y5V型陶瓷材料。方法采用固相法掺入纳米CuO制备一系列的BCSTZS陶瓷。通过XRD,TEM和SEM对样品进行表征,并测试陶瓷的介电性能。结果在低温烧结时,陶瓷的密度和介电常数随CuO掺杂量的增加而增大,纳米CuO可以将BCSTZS陶瓷的烧结温度降低到1 150℃。当纳米CuO含量为1.5%(质量分数)时,BCSTZS陶瓷材料满足EIA Y5V标准,其εmax=8 690,介质损耗为1.67%,绝缘电阻率为5×1013Ω.cm。结论采用纳米CuO为助烧剂制备的BCSTZS陶瓷具有气孔率小、密度较大,晶粒大小一致且分布均匀的特点,采用该方法可以在低温下得到满足Y5V标准的BSCTZS基陶瓷材料。该研究具有重要的应用前景。
