Formation of intermediate phases on synthesis of superconducting ceramics YBa2Cu3O7-x
- 1. AN Armyanskoj SSR, Erevan (Armenia). Inst. Fizicheskikh Issledovanij
Description
Process of phase formation during synthesis of YBa2Cu3O7-x from mixture of Y2O3, BaCO3 and CuO was investigated. Mixture heating in 650-900 deg C range results to partial decomposition of BaCO3 and formation of intermediate phases. Synthesis proceeds without limiting reactions and terminates at 880 deg C with further increase of temperature. Method of reproducible preparation of YBa2Cu3O7-x ceramics with superconducting transition width of less than 1 K was developed
