Title: Influence of residual phases on the properties of YBa{sub 2}Cu{sub 3}O{sub 7{minus}x}

Abstract

The partial melting in YBaCuO incompletely synthesized powders occurring at temperatures below the peritectic decomposition of the 123 (YBa{sub 2}Cu{sub 3}O{sub 7{minus}x}) compounds is related to the presence of residual phases. The results showed that the final ceramic has got a high porosity, which is independent on the temperature of sintering, the double grain size distribution and two transition temperatures up to the sintering temperature 940 C as a consequence of a higher content of the residual carbonate. The sintering at higher-temperature improved superconducting properties of ceramics. This progress is connected with cracking of large grain ceramic and with the decomposition of carbonate BaCO{sub 3}.
