Abstract

Abstract We investigated behaviour of YBa2Cu3O7 (Y123) powder and YBCO bulk superconductor prepared by Top Seeded Melt Growth process in atmospheres with different oxygen partial pressure by Differential Thermal Analysis simultaneously with Thermo – Gravimetric and Microstructural analysis. The peritectic melting temperature of studied systems was measured and the stability of Y123 powder and Y123/Y2BaCuO5 composite in low oxygen atmosphere was estimated.
