Abstract
An electrical resistance element of the molybdenum silicide type including at least one hot zone and at least two lead-in conductors. The hot zone includes an homogenous silicide material that contains molybdenum and tungsten having the chemical formula Mo.sub.x W.sub.1-x Si.sub.2, where x is between 0.5 and 0.75. From 10% to 40% of the total of the silicide material is replaced with at least one of the compounds molybdenum boride or tungsten boride; those compounds are present in the silicide material in particle form.
