Срібловмісна ВТНП кераміка на основі сполуки YBa2Cu3O7-8

Abstract

The present work is a review of chemical aspects of silver containing HTS based on YBa2Cu3O7-8 compound. The main attention has been concentrated to phase transformations in Y-Ba-Cu-O-Ag system. The interaction between silver substrate and HTS ceramics must be taken into consideration at elaboration of technique of synthesis (temperature conditions and ceramics composition). The composition YBa2Cu3O7-8 + Y2BaCuO5 and eutectic mixture YBa2Cu3O7-8 + Y2BaCuO5 + BaCuO2 are proposed for qualitative YBa2Cu3-хAgхO7-8 crystal are proposed.
