Abstract: Oxide thermistor compositions which comprise 100 atomic % of at least four kinds of cations which are (1) Mn ion, (2) Ni ion, (3) at least one kind of ion selected from the group consisting of Cu, Fe, and Cr, and (4) one kind of ion selected from the group consisting of Cr, Zr, and Li. These compositions have lower resistivity with higher B-constant and exhibit a high stability of resistance.

Abstract: A thermistor material of between 99% and 50% by weight of praseodymium oxide and 1 to 50% by weight of zirconium oxide provides a stable thermistor with desired resistance value changes over a temperature range of 100.degree.C to 600.degree.C. Other selected oxides may be used in place of zirconium. Small amounts of indium or gallium oxides can also be added to the mixture to lower the resistivity and temperature coefficient of resistance.
