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.

Claims (40)

1. An electric heater comprising:

a resistor deposited on a substrate, said resistor giving off heat in proportion to applied electrical power;

said resistor formed of at least one noble metal and an oxide selected from the group consisting of yttrium oxide, cerium oxide, zirconium oxide, and combinations of these;

a first conductor formed from a first conductor material, said first conductor electrically connected to said resistor; and

a second conductor formed from a second conductor material, said second conductor electrically connected to said resistor;

a sheath enclosing said conductors, said sheath is formed of at least one noble metal and an oxide selected from the group consisting of yttrium oxide, cerium oxide, zirconium oxide, and combinations of these;

said sheath being electrically insulated from said first and said second conductors.

2. The electric heater of claim 1 wherein the sheath material further comprises yttrium oxide and zirconium oxide.

3. The electric heater of claim 1 wherein the first conductor material and the second conductor material are the same.

4. The electric heater of claim 3 wherein the first conductor material and the second conductor material are different than the sheath material.

5. The electric heater of claim 1 wherein the noble metal is a platinum group metal.

6. The electric heater of claim 5 wherein the noble metal is platinum.

7. The electric heater of claim 6 wherein the oxide is dispersion hardened within grain boundaries and a main body portion of the platinum.

8. The electric heater of claim 5 wherein the noble metal is platinum rhodium alloy.

9. The electric heater of claim 8 wherein the oxide is dispersion hardened within grain boundaries and a main body portion of the platinum rhodium alloy.

10. The electric heater of claim 9 wherein the platinum rhodium alloy is Pt-10% Rh.

11. An electric heater comprising:

a resistor formed of at least one noble metal and an oxide selected from the group consisting of yttrium oxide, cerium oxide, zirconium oxide, and combinations of these;

a first conductor formed from a first conductor material, said first conductor electrically connected to said resistor; and

a second conductor formed from a second conductor material, said second conductor electrically connected to said resistor; and

an electrical power source, electrically connected to said resistor via said first and second conductors;

said resistor providing heating to an area proximate to said resistor based on an applied electrical power from said electrical power source;

a sheath enclosing said conductors, said sheath is formed of at least one noble metal and an oxide selected from the group consisting of yttrium oxide, cerium oxide, zirconium oxide, and combinations of these;

said sheath being electrically insulated from said first and said second conductors.

12. The electric heater according to claim 11 wherein said resistor is deposited on a substrate.

13. The electric heater according to claim 11 wherein said resistor is wound around an insulator.

14. A method for manufacturing a heater comprising the steps of:

forming a resistor 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;

electrically connecting a first conductor to the resistor, the first conductor formed from a first conductor material;

electrically connecting a second conductor to the resistor, the second conductor formed from a second conductor material;

providing heating of an area adjacent to the resistor when electrical power is applied to the resistor via the first and second conductors; and

enclosing the conductors in a sheath that is formed of at least one noble metal and an oxide selected from the group consisting of yttrium oxide, cerium oxide, zirconium oxide, and combinations of these where the sheath is electrically insulated from the first and the second conductors.

15. The method according to claim 14 further comprising the step of positioning the resistor on a substrate.

16. The method according to claim 14 wherein the sheath material further comprises yttrium oxide and zirconium oxide.

17. The method according to claim 14 wherein the noble metal is a platinum group metal.

18. The method according to claim 17 wherein the noble metal is platinum.

19. The method according to claim 18 further comprising the step of dispersion hardening the oxide within grain boundaries and a main body portion of the platinum.

20. The method according to claim 17 wherein the noble metal is platinum rhodium alloy.

21. The method according to claim 20 further comprising the step of dispersion hardening the oxide within grain boundaries and a main body portion of the platinum rhodium alloy.

22. The method according to claim 21 wherein the platinum rhodium alloy is Pt-10% Rh.
