Processing, properties, and applications of Y-Ba-Cu-O superconductors

Journal Article


Abstract


  • Although ceramic superconductors were discovered less than two years ago, the amount of research work and number of resultant publications have been enormous. The present work reviews a number of the aspects of this work in Australia and elsewhere. The five principal areas discussed are phase equilibria of the system 1/2 Y2O3-BaO-CuO, chemical substitutions in this system, microstructure and crystallography, processing, and applications of thin films and bulk materials. The phase equilibria in the Y-Ba-Cu-O and other chemically substituted systems are important to the processing and utilization of materials based on the YBa2Cu3O7-x phase. While the subsolidus and liquidus relations are still tentative, the crystallography has been well established. The resultant microstructures are typical of porous polycrystalline ceramics and depend largely on the processing. which is discussed for both bulk materials and deposited films. The applications of both types of materials are discussed in light of their electrical and magnetic properties.
