Abstract

The freeze-drying method of synthesizing powders of the superconducting oxide YBa2Cu3O7-δ is described. This process produces homogeneous, submicron powders of high purity. The effects of salt selection, solution concentration and pH on the process are described. Some evaluation of the sintering behavior and the effects on critical current density are included.
