Processing and Properties of High Temperature Ceramic Superconductors
31 January 1988
A short history of oxide superconductors will be reviewed leading to the discovery of the Ba sub 2 YCu sub 3 O sub 7 compound superconducting at > 90K. The unique features of the structure of this compound will be described along with its electrical properties. This family of superconductors cannot be processed using metal fabrication methods due to the brittle mechanical properties of this ceramic material. The applicable processing methods for fabrication of thin films and bulk articles will be reviewed.
