Abstract
A process for preparing a superconducting, ceramic material with an increased critical current is described. In this process, the materials used to form the superconducting material are mixed with at least one inorganic salt, and the mixture containing the salt is then heat treated. The salt is then leached from the heat-treated mixture.
