<p>The invention is for an electrical resistance element of the molybdenum disilicide type. It refers to elements which mainly are composed of silicide compounds, where molybdenum is the main part of the metal component. The element according to the invention can be used at higher operation temperatures than previously known elements of this kind. This means about 1800°C furnace temperature. According to the invention this is achieved by substituting part of the molybdenum in the molybdenum silicide structure for tungsten. When different properties of the material are taken into account it is concluded that 25-50 atomic % molybdenum shall be substituted for by tungsten. The resistance elements are produced according to previously known methods.</p> |
