摘要

利用烧结工艺路线控制纳米相偏析效应，首次研制出化学成分为cu0.1 ni0.8 co0.2 mn1.90 o4的混合Ni-Co-Cu氧锰尖晶石，有望应用于高精度NTC热敏电阻。结果表明，在高温下陶瓷的储热过程中，铌酸盐相对陶瓷的寄生降解起决定性作用。

Sintering-modified oxymanganospinel ceramics for NTC thermistor application

Mixed Ni-Co-Cu oxymanganospinels of Cu0.1Ni0.8Co0.2Mn1.9O4 chemical composition are first developed for possible application as high-precise NTC thermistors using nanophase segregation effects controlled by sintering technological route. It is shown that rack-salt NiO phase in these ceramics occurs a decisive role on parasitic degradation caused by thermal storage of the ceramics at the elevated temperatures.
