Abstract
Improved anchoring of heating elements of a resistance heater to thermally stressed single crystals is achieved by embedding the individual heating element in a recess in the single crystal and permanently joining this to the heating element by a porous sintered composition. The sintered composition is formed by the heat treatment of a suspension that in addition to other components, contains material with the same chemical composition in powdered form as that of the single crystal.
