Abstract

YBa$_2$Cu$_3$O$_{x}$ samples with different amounts of $Y_2$BaCuO$_{5}$ were prepared by MPMG (Melt Powder Melt Growth) method. The effects on the size of initial particles and Ag addition for $Y_2$BaCuO$_{5}$ distribution in YBa$_2$Cu$_3$O$_{x}$ were invesgated. The samples prepared by the melting process usually have large grains up to several ㎣ and precipitates of $Y_2$BaCuO$_{5}$. The distribution of the $Y_2$BaCuO$_{5}$ particles in the samples depends on the size of initial particles and the amounts of Ag addition.Ag addition.
