| Abstract: | Mg Mn Fe O thermister features high resistance and low material constant B value by reduction.Different from normal NTC thermister,its B value increases continuously by a big extent with rising temperature.This article studies the effect of reduction condition,material constituent, and sintering temperature on the electrical character.It also explains the mechanism of variable B value character of Mg Mn Fe O thermister. |

| Keywords: | variable B value wide temperature range NTC thermister |
