PTC SEMICONDUCTOR CERAMIC COMPOSITION, METHOD FOR PRODUCING THE SEMICONDUCTOR CERAMIC AND HEATING DEVICE AND USE

ANGERMANN HANS-HEINRICH / WINTRICH KLAUS / SEIFERT TORBEN

A semiconductor ceramic composition may include, as a main component, a BaTiO3-based compound according to the formula [BabCacSrsPbpRx][TitAaMnm]O3+z. R may represent at least one element selected from a group consisting of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb. A may represent at least one element selected from a group consisting of V, Nb, and Ta. The variables b, c, s, p, x, t, a, m, and z may be defined as: b=1−c−s−p−x; 0<0.51; 0.490

<(t+a+m)<1.011575; 0.9889
