Abstract
The invention relates to a high temperature-resistant composite which consists of at least one part of molybdenum or a molybdenum alloy, and at least one part of graphite, which parts are joined together by means of a zirconium solder. A two-ply interlayer, consisting of a 0.01-0.5 mm thick layer of vanadium, and a 0.1-0.5 mm thick layer of tungsten, tantalum or niobium, is arranged between the part of molybdenum or the molybdenum alloy and the zirconium solder. The layer structure substantially prevents the formation of a eutectic between molybdenum or the molybdenum alloy and the zirconium solder, thereby preventing the reduction of the maximum permissible use temperature of the composite.
