摘要：An electric heating element is disclosed that is capable of cyclic operation attemperatures in excess of 2500 DEG F in an air atmosphere. The heating element consistsessentially of molybdenum wire as a substrate and a relatively thin layer of molybdenumdisilicide over the substrate. A process consisting of heating the coils in a non-oxidizingatmosphere with boron silicide, sodium fluoride and silicon produces the heatingelements under controlled time and temperature conditions.
