Sm-doped YBCO high Tc superconductor was directionaly grown by zone melt growth process in airatmosphere. Cylindrical green rods of (Sm/Y)1.8Ba2.4Cu3.4O7 - x[(Sm/Y)1.8] oxides were fabricated by cold isostatic pressing(CIP) method using ruber mold. Based on the variation of melting temperature and growth rate, the microstructure andsuperconducting properties were systematically measured by using optical micrographs, TEM and SQUID magnetometer. Inthis study, optimum melting temperature and growth rate were 1085oC and 3.5 mm/hr respectively. Nonsuperconducting(Sm/Y)2BaCuO5 inclusions of (Sm/Y)1.8 superconductor were uniformly distributed within the superconducting (Sm/Y)Ba2Cu3O7 - x matrix. The directionaly melt-textured (Sm/Y)1.8 superconductor showed an onset Tc 90 K and sharpsuperconducting transition.
