Influence of an electric current on the crystallization of YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} in BaO/CuO/CuO{sub 0.5} flux melts
The influence of an electric current on the ternary BaO/CuO/CuO{sub 0.5} system and the quaternary YO{sub 1.5}/BaO/CuO/CuO{sub 0.5} system has been investigated by modified differential thermal analysis. Increasing the current in the ternary system leads to the crystallization of an additional phase. In the quaternary system they find a splitting of the solidification of the residual melt BaO/CuO/CuO{sub 0.5} indicating the formation of two different eutectics. In both systems, they find a preferential deposition of material at the positive electrode. Crystal growth experiments including electric current show a preferential formation of YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} crystals at the positive electrode.
