Abstract
An electric resistive heater having an extended temperature range and repeatable heating characteristics. The resistor being formed of a material having at least one noble metal and an oxide selected from the group consisting of yttrium oxide, cerium oxide, zirconium oxide, and combinations of these. The resistor may further have the oxide dispersion hardened within grain boundaries and a main body portion of the noble metal.
Claims27
An electric heater comprising:
- a resistor deposited on a substrate, said resistor giving off heat in proportion to applied electrical power;
