Abstract
The influence of an electric current on the ternary BaO/CuO/CuO0.5system and the quaternary YO1.5/BaO/CuO/CuO0.5system 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 we find a splitting of the solidification of the residual melt BaO/CuO/CuO0.5indicating the formation of two different eutectics. In both systems we find a preferential deposition of material at the positive electrode. Crystal growth experiments including electric current show a preferential formation of Yba2Cu3O7−xcrystals at the positive electrode.
