| ABSTRACT |
|
Single crystals of YBa2Cu3O7-x have been grown in BaCuO2 flux at temperature of 125$0^{circ}C$ and examined using XRD, EDAX and light microscopy. The YBCO crystals were grown in a cavity which was formed by the reduction of CuO and became large by the directional solidification in the crucible. The observed crystal growth habit is square planar with the c-axis normal to the plane. The surface morphology of grown crystals were growth ledges and growth sprial paterns on a (001) face. |
