A method of increasing the length of life of heating elements that consist essentially of molybdenum-silicide, and alloys thereof, when the elements are operated at a low temperature, such as at a temperature ranging from 400-600° C. The heating element material contains Mo(Si<SUB>1-x</SUB>Al<SUB>x</SUB>)<SUB>2</SUB>, and that material contains sufficient aluminum to substantially prevent the formation of pest. |
