摘要
文章介绍了以Ｆｅ２Ｏ３和Ｃｕ２Ｏ为主成分的陶瓷材料的负阻特性，分析论述了Ｃｏ２Ｏ３、Ｂｉ２Ｏ３以及ＭｎＯ２掺杂对Ｆｅ－Ｃｕ系陶瓷材料负阻性能的影响，实验制得负阻系数ｎ＞１０，电压Ｖｐ＞２００的负阻性能良好的陶瓷材料。
This paper described the negative resistance characteristics of Fe Cu system ceramics, and investigated the effects of Co 2O 3,Bi 2O 3 and MnO 2 dopants on the negative resistance characteristics of Fe Cu system ceramics. Some Fe Cu system ceramics with good negative resistance characteristics( n >10, V p>200) were obtained.
