High Temperature Superconductors: Crystal Chemistry and Electrochemistry
05 June 1988
The discovery of superconductivity at temperatures above the boiling point of nitrogen in Ba sub 2 YCu sub 3 O sub 7 has sparked an explosion of interest in the chemistry and properties of this new material. The growth of large single crystals of Ba sub 2 YCu sub 3 O sub 7 for investigations of structural property relationships, impurity effects and physical characterization directed towards the understanding of superconductivity in this potentially important new material will be discussed. In addition, the reaction chemistry of this and related materials in ceramic form has been probed by electrochemical techniques including rotating ring-disk voltammetry. Understanding of the reactions of these materials in water-containing environments will be important to future uses for these materials.
