Summary

HIGH TEMPERATURE SUPERCONDUCTORS (COPPER OXIDE CERAMICS) HAVE THE POTENTIAL FOR ENORMOUS ECONOMIC IMPACT. BUT, BEFORE THEIR TRUE ECONOMIC POTENTIAL CAN BE REALIZED, IT IS NECESSARY TO DISCOVER THEIR THERMAL, ELECTRICAL AND MECHANICAL PROPERTIES AND TO DEVELOP METHOD OF MANUFACTURING THE CERAMICS RELIABLY. IN FACT, THE POPULAR PRESS HAS FOCUSED ON CRITICAL TEMPERATURE, BUT CURRENT DENSITY IS MORE IMPORTANT TO THE ENGINEER AND ECONOMIST: MOST APPLICATIONS HAVE AN OPERATING CURRENT DENSITY WHICH IS 10 TO 100 TIMES HIGHER THAN CRITICAL CURRENT DENSITIES MEASURED SO FAR IN WIRES AND TAPES MADE FROM CERAMIC SUPERCONDUCTORS.
