A process of manufacturing a chromium alloyed molybdenum silicide portion of a heating element comprising the steps of: forming a mixture of a chromium powder and a silicon powder; reacting the mixture to a reaction product in an inert atmosphere at a temperature of at least 1100° C. but not more than 1580° C.; converting the reaction product to a powder comprising CrSi; forming a powder ceramic composition by mixing the powder comprising CrSiwith a MoSipowder and optionally with an extrusion aid; forming the portion of the heating element; and sintering the portion of the heating element in a temperature of from about 1450° C. to about 1700° C.; characterized in that the chromium powder and the silicon powder are provided separately to the mixture.

Process for manufacturing a chromium alloyed molybdenum silicide portion of a heating element

The present disclosure relates to a heating element, wherein at least one part of the heating element is manufactured from a molybdenum disilicide composition and wherein in the molybdenum disilicide composition, molybdenum is substituted by chromium according to (MoCr)Siand x is in the range of 0.16≤x≤0.19.

Heating element comprising chromium alloyed molybdenum disilicide and the use thereof

The present disclosure relates to a heating element comprising at least two parts which are composed of different molybdenum disilicide-based compositions, wherein at least one of the molybdenum disilicide-based parts is based on a chromium-alloyed based molybdenum disilicide composition ((MoCr)Siwhere x is of from 0.05 to 0.25); and at least one part is based on a molybdenum disilicide-based composition comprising more than or equal to 90 weight % Mo(Si,AI). The present disclosure also relates to the use of the heating element.

Heating element

The present disclosure relates to a molybdenum silicide based composition comprising aluminum oxide (AlO) and to the use thereof in high temperature applications.
