Abstract
An electrical resistance element of a silicide phase according to the formula Mo(Si Al ) , which phase forms alumina on the surface of the element. The element is intended to be used in connection with sintering of metal powder. Because of its surprisingly good ability to form an alumina layer on the surface, this material has shown to be very resistant against corrosion at high temperatures over 1500° C. in both reducing and oxidizing atmosphere.
