  • Medium temperature thermistor
    Patent number: 3950273
    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.
