Abstract

Disclosed are means and method for forming elastic connection between ceramic and metallic structural elements. The means comprises a ceramic structural element; a metallic structural element having thermal and elastic properties different from those of the ceramic structural element; and a connecting element connecting the ceramic and metallic structural elements and comprising an insulating resilient body of ceramic material having a thermal conductivity of between about 0.02 and 0.25 W/cmK at a temperature difference between the ceramic and metallic structural elements of from about 100 to 1500 Centigrade degrees, an elastic modulus of between about 5000 and 150,000 N/mm.sup.2 and being substantially free of plastic deformation.
