ABSTRACT:
A high temperature thermistor composition comprising a spinel-type Mg Al.sub.2 O.sub.4 and perovskite-type La CrO.sub.3 or (La, Sr) CrO.sub.3 is usable for the temperature range from 400.degree. to 600.degree. C, and a high temperature thermistor composition comprising spinel-type solid solution Mg(Al, Cr).sub.2 O.sub.4 and perovskite-type solid solution (La, Sr) CrO.sub.3 or LaCrO.sub.3 is usable for a higher temperature range up to 1000.degree. C.
