1. An NTC compound comprising:
a ceramic material of a Mn—Ni—O system as a main constituent,
wherein the Mn—Ni—O system has a general composition NixMn2O4-δ,
wherein y corresponds to a molar fraction of Ni of a total metal content of the ceramic material of the Mn—Ni—O system, which is defined as c(Ni):(c(Ni)+c(Mn)), and
wherein the following applies:
0.500<x<0.610 and 0.197<y<0.240; and
at least ZrO2 as a dopant,
wherein a corresponds to a content of ZrO2 and is based on 100% by weight of NixMn2O4-δ, and
wherein the following applies:
0.58 wt %≤a≤0.72 wt %.
