摘要： PURPOSE:To obtain a structure oriented along a metal foil by combining a thick film material prepared by a doctor blade method, etc., with a metal foil and maintaining the resulting composite in a partly melting condition. CONSTITUTION:A calcined powder of an oxide superconductor is mixed with a polyvinyl-based binder, a plasticizer, and a dispersing agent, the mixture is molded by a doctor blade method to give a thick film-like molded body 1, the thick film is cut, and then the cut film is laminated on a cut silver foil 2. The resulting bilayered thick film 1, 2 is processed for removing soot and heat-treated successively. That is, the thick film-like molded body 1 and the metal foil 2 are kept at a temperature where the oxide superconductor powder is partly melted. In this method, orientation of oxide superconductor crystal particles and binding the particles are accelerated and an oxide superconductor tape material with high critical current density is obtained.

摘要： PURPOSE:To perform mechanical, electrical junction of oxide superconductor tapes by laminating a primarily sintered oxide superconductor tape and a non-superconductor tape having notches alternately and performing secondary sintering after compression of a resultant laminate. CONSTITUTION:Primarily sintered compacts 21 of each tape like oxide superconductor and non-superconductor tapes 22 which are equipped with notches 23 and are made of silver, gold, and platinum and the like are laminated alternately. In such a case, oxide superconductors 21 which come into contact with both faces of each non- superconductor tape 22 form cavities at the notches 23 and are facing each other. When this laminate is compressed, primarily sintered compacts 31 become refined and their preciseness reduces thickness of each sintered compact and then, cavities which are found in the notches disappear. The primarily sintered compacts 31 located at upper and lower non-superconductor tapes 32 are pressed at these parts 33. Further, the compression makes crystal perform orientation to improve superconducting characteristics. Moreover, when secondary sintering is performed, the degree of coupling between crystal particles is improved. Junction which is made between oxide superconductor tapes and is superior in electrical, mechanical systems is thus obtained.
