摘要
A method of increasing the useful life of heating elements that consist essentially of molybdenum silicide and alloys thereof, wherein the heating elements operate at high temperatures in heat treatment processes and generally rest against the floor and/or the ceiling of a furnace. The heating elements contain aluminum to an extent sufficient to maintain a stable, slowly growing layer of aluminum oxide on the surfaces of the heating elements, and the heating elements are placed in direct abutment with an aluminum oxide brick material.
