PZT/Y_(0.9)Ca_(0.1)Ba_2Cu_4O_8及Ag_2O掺杂的复合氧化物陶瓷的NTC效应

The NTC Effect of PZT/Y_(0.9)Ca_(0.1)Ba_2Cu_4O_8 and Ag_2O-Doped Composites

报道了压电材料PZT中掺杂超导粉Y0 .9Ca0 .1Ba2 Cu4O8,而超导粉中又有Ag2 O的掺杂。这种复合氧化物陶瓷的制备方法及电导率的测试结果 ,表明材料具有很强的NTC效应。

High T c superconductors Y 0.9 Ca 0.1 Ba 2Cu 4O 8 is doped in piezoelectric ceramic PZT system and Ag 2O is doped in Y 0.9 Ca 0.1 Ba 2Cu 4O 8 system.The composite oxide ceramics are prepared and electrical conductivity are determined.Results show that the material have stronger NTC effect.
