Mechanism of Microstructure Development in Melt-Textured Y-Ba-Cu-O Superconductors

Abstract

The purpose of this program was to study the growth process in melt-texturing of YBCO and reduce the overall processing time. Melt-texturing had been used to achieve high current densities in bulk YBCO as well as attain high levitation forces and trapped fields. The melt-texturing process was however too slow to be economical for large-scale manufacturing. The objective of the program was modified in September 1996 towards development of YBCO superconducting thin films using Metal Organic Chemical Vapor Deposition (MOCVD) on biaxially-textured metal substrates. Both the buffer layer and YBCO deposition processes were developed for metal substrates.
