Composite Ceramic Superconducting Wires for Electric Motor Applications
Abstract
This is the First Quarterly Report of a program to produce practical htsc wires, and build a htsc electric motor using this wire. The htsc ceramic wire will be a flexible composite of many fine ceramic filaments clad with copper or aluminum. The three basic elements of this method are: 1) spinning polymer-containing 'green' fibers; 2) sintering the fibers to make bare superconducting ceramic filaments; and 3) cladding the filaments with copper. Albany International Research Corporation (AIResCo) is working with CPS to improve the green fiber spinning process and bring it to pilot scale production. During this Quarter, most of the fibers were prepared from a Rhone-Poulenc powder. This material was suitable for spinning and highly sinterable, but contained excess copper oxide. Much effort went to scaling up in-house powder production of highly phase pure YBa2Cu3O7 powder to production rates adequate to supply the development program. The influence of powder characteristics on fiber spinning and sintering in now being studied to optimize the powder for the wire manufacturing.
