preparing the stress- relaxing layer (3) of low thermal expansion metal e.g. Nb, Ta, W, Mo or soft metal e.g. Ni, Ti, Cu; coating Ag-Cu-Ti alloy as film soldering material (2,4) on both surfaces of the stress- relaxating layer (3); inserting it between ceramic (1) e.g. Al2O3, ZrO2, Si3N4 and metal (5) e.g. iron, steel; soldering the prepared body in 10-5 Torr vacuum furnace; or solid-diffusing at 90 % temperature of Ag-Cu-Ti alloy melting point. The produced composite has a high bonding strength.
