Superconducting thick films were grown on single crystals MgO and YSZ by electrophoretic deposition with Y2BaCuOs(Y211) addition. YBCO thick films were then accomplished by sintering the precursor films above the peritectic temperature. Single crystals of MgO (3×3×0.5mm3) were used as top-seed to control crystal structure of the thick films. As shown by scanning electron microscopy, the morphologies of YBCO/YSZ and YBCO/MgO thick films are spherulitic texture and platelet type. The critical temperature is ～89 K for the YBCO/YSZ thick film; the onset transition temperature is 86.4 K and the transition width is ～3 K for YBCO/MgO thick film. The critical current densities (as determined by Bean model) are, in A/cm2, 3870 (77K) for YBCO/YSZ thick films and 2399 (77K) for YBCO/MgO thick films, which are comparable to the best Jc reported of the thick films prepared by the same method.
