Claim Text:
1. A method for producing an alloy powder comprising the steps of: mixing at least one oxide selected from the group consisting of titanium oxide, zirconium oxide and hafnium oxide with at least one element selected from the group consisting of Ni, Cu, Ta, W, Re, Os and Ir, and a reducing agent to form a mixture; heating the mixture in an oven in an argon atmosphere until a reduction reaction begins and a reaction product is obtained; and leaching, washing and drying the reaction product to yield the alloy powder; wherein the at least one oxide has a mean particle diameter (FSSS) of 0.5 to 20 μm, a BET specific surface area of 0.5 to 20 m wherein the alloy powder has a burning time of 10 s/50 cm to 3000 s/50 cm, an ignition energy of 1 μJ to 10 mJ, an average particle size of from 1 to 8 μm, a BET specific surface area of 0.2 to 5 m
