摘要：

The calcination of coprecipitated Y-Ba-Cu oxalates and hydroxide-carbonates and of their single components were compared. The perovskite formation of YBa2Cu3O7-x, and the phase transformations and decomposition of the 1-2-3 phase were investigated thermoanalytically and by X-ray diffraction. The possibilities of chemico-thermal influences on the phase formation are discussed. © 1990.
