FIELD: obtaining joints of increased irradiation stability. SUBSTANCE: heating the joint to be soldered is accomplished at a rate of 60-140 C/s from a temperature approximating the vitrifying point of the glass phase incorporated into the ceramic composition the process being completed at a joint temperature near the metal fittings melting point. The obtained heating conditions result in temperature gradients appearing at the ceramics surface with a glass phase portion being positively extruded from the inner layers to the contact surface. EFFECT: increased durability and irradiation stability of the joint.
