Abstract
Official abstract text for this publication.
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 (Mo1-xCrx)Si2 and x is in the range of 0.16≤x≤0.19.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heating element composed of at least two molybdenum disilicide-based parts, wherein at least one part is based on a molybdenum disilicide composition comprising more than 90 weight % of (Mo 1-x Cr x )Si 2 and wherein x is in the range of 0.16≤x≤0.19; and wherein at least one part is based on a molybdenum disilicide composition comprising a) more than or equal to 90 weight % MoSi 2 balance is aluminosilicate and/or SiO 2 or b) more than or equal to 90 weight % (Mo,W)Si 2 balance is aluminosilicate and/or SiO 2 . 2. The heating element according to claim 1 , wherein x is in the range of 0.16≤x≤0.18. 3. The heating element according to claim 1 , wherein x is in the range of 0.165≤x≤0.175. 4. The heating element according to claim 1 , wherein the molybdenum disilicide is substituted by chromium comprises from 95 weight % (Mo 1-x Cr x )Si 2 . 5. The heating element according to claim 1 , wherein the composition of molybdenum disilicide is substituted by chromium has a balance of aluminosilicate and/or SiO 2 . 6. The heating element according to claim 1 , wherein an entirety of the heating element consists of the molybdenum disilicide composition. 7. The heating element according to claim 1 , wherein the heating element consists of two parts. 8. The heating element according to claim 1 , wherein the heating element consists of three molybdenum disilicide-based parts wherein two parts of the heating element are based on the same molybdenum disilicide-based composition and one part of the heating element is based on a different molybdenum disilicide-based composition. 9. Use of a heating element according to claim 1 in a furnace. 10. A furnace comprising a heating element according to claim 1 .
