Microstructural Evolution of YBa2Cu3O7-x Using Microwave Energy,
Abstract
Discs of YBa2Cu3 O sub 7-x were sintered at 2.45 GHz in a Raytheon modelQMP2101B-6 microwave oven using hybrid heating. Heating YBa2Cu3 O sub 7-x solely by microwaves is feasible, but a silicon carbide susceptor was used to insulate the discs and provide a more uniform thermal environment. In order to begin with a uniform green microstructure, the discs were slip-cast from a non-aqueous dispersion containing fine YBa2Cu3 O sub 7-x powder. The effects of varying times and temperatures on the microstructural uniformity, densification, and grain growth were investigated using optical and quantitative microscopy.
