Abstract
Superconducting powders were synthesised by solid-state reaction. They were ball-milled, and pressed into pellets. It was found that particl e size prior to sintering has a substantial influence on the propertie s of Bi-based bulk superconductors, such as reactivity, phase homogene ity and T-c values. Powders of fine particle size were found to show l ow T-c values.
