YBa2Cu3O7-x/ZrO2 composites mere prepared and sintercd at different conditions. The microstructure was observed by polarised light microscopy and SEM. The composites were characterized by DTA, XRD and EDX analysis. The growth morphology of YBCO is radically changed by ZrO2 addition and it is believed that its appearance is mainly caused by the existence of the BaZrO3 and liquid phases.
