补充资料:正温度系数热敏陶瓷阻-温特性曲线
分子式:
CAS号:

性质:描述正温度系数热敏陶瓷电阻率与温度关系的曲线。钛酸钡基PTC热敏陶瓷阻-温特性曲线。电阻率随着温度的升高,先是降低,当达到某一值Tmin时,曲线出现极值,经过极值后电阻率随温度升高而急剧上升,此时对应的温度Tb称为开关温度。电阻率随温度上升达到最大值时所对应的温度为Tm。经过Tm后,阻温特性曲线发生弯曲,电阻率开始逐步降低,此时对应的温度为Tp。温度处于Tb至Tm之间时,热敏陶瓷呈现正温度系数(PTC)特性。其电阻温度系数αT= ,式中Rb,Rp为Tb,Tp温度下的相 应零功率电阻值。αT大于10%/℃,为开关型热敏陶瓷电阻器。αT小于10%/℃,为缓变型热敏陶瓷电阻器。
