Abstract
Methods of manufacturing thermocouples having a first thermoelement wire comprises a molybdenum-lanthanum based material and a second thermoelement wire comprises a phosphorus-doped niobium, may involve exposing a first thermoelement wire and a second thermoelement wire to a temperature in a range extending from about 50° C. to about 60° C. above an intended operational temperature of the first and second thermoelement wires and until a rate of change of a normalized voltage output of the first thermoelement wire and the second thermoelement wire is about 0.001 normalized Volts per hour or less.
