| 简介 | A ceramic material with a negative temperature coefficient of specific resistance has the general formula [{(SE1III, SE2III)1−x(M1II, M2II)x}(Cr1−y−zMny(Me1III, Me2III)z)O3]. In this formula, SE1III and SE2III are different rare-earth metal cations, M1II and M2II are selected from CaII, SrII, and Me1III and Me2III are redox-stable, trivalent metal cations, wherein the following applies with respect to the parameters : 0 | ||
