Method to improve the life span of a heating element of a molybdenium disilicide at lower temperatures

摘要

A method of increasing the length of life of heating elements that consist essentially of molybdenum-silicide and alloys of this basic material, when said elements are operated at a low temperature, such as at a temperature ranging from 400-600° C. The invention is characterized in that the heating element material contains Mo(Si1-xAlx)2, where said material is caused to contain sufficient aluminium to substantially prevent the formation of pest.
