Method for producing silver contact fields in the superconductor from YBCO ceramics

摘要

method of manufacturing contact fields with silver in nadprzewodnikach ceramic ybco, to combine nadprzewodnika with metallic removals is that layer of ceramic powder ybco is placed in the steel matrix of the desired shape and size of cross section, between the two warst you silver granules and all are pressed under pressure not lower than 50 mpa.then obtained wyprasku0119 subjected to heat treatment in an atmosphere of oxygen. this method enables the making of diffusive couplings with very good mechanical properties (permanent combination between silver and ceramics) and very good electrical properties (linear omowa characteristics and in combination).
