Number 7 (Story #2), November 1, 1990 by Phillip F. Schewe and Ben Stein HIGH TEMPERATURE SUPERCONDUCTOR (HST) APPLICATIONS ,slow in coming, may pick up soon. For example, "melt-textured" processing, involving partial melting and then cooling the HST compounds, has resulted in better critical current densities in bulk samples, up to 105 amperes/cm2 at the University of Houston, and a higher tolerance for magnetic fields. Ease of processing and mechanical flexibility, however, must be improved. Malleability may be increased by imbedding carbon fibers in the compounds. Meanwhile, advances in HTS thin films offer the possibility of applications in the designing of superconducting quantum interference devices (SQUIDS), high-resolution antennas, and fast transistors.
