【摘要】 为了优化CTR（CriticalTemperatureResister）产品性能,从微观上分析CTR晶粒体相变临界特征和粒界的电势垒,得出CTR临界阻温特性是由晶粒体导电性能和粒界电势垒共同决定,即“晶粒体-粒界”模型。运用此模型对不同配料比样品的临界阻温特性进行分析,得出V₂O₅P₂O₅Fe₂O₃配料比是影响CTR性能的关键因素。更多还原

【Abstract】 In order to enhance the CTR（Critical Temperature Resister） product performance, from micrograph the critical characteristic of phase change of the CTR crystal grain body and the electricity potential barrier between grains were analysed. The CTR critical resistance temperature characteristic is decided together by the crystal grain body electric conductivity and the grain of electricity potential barrier. The model carries on the analysis using "the crystal grain body-grain" to the different ingredient compared to the sample critical resistance temperature characteristic, obtains V₂O₅:P₂O₅:Fe₂O₃ ingredient ratio is affects the CTR performance the key aspect.更多还原
