(Sm,Eu,Gd)Ba2Cu3O7-x (SEG123) superconductors were synthesized by the melt process in a reduced oxygen atmosphere. We could grow a relatively large grain SEG223 crystal by using a MgO (100) seed. Microstructural investigations revealed that the ratio of Sm: Eu: Gd in the 123 matrix was 1 : 1 : 1 and the same as the starting composition, indicating that mixing of three different rare earth elements is very uniform. The melt-processed SEG123 system showed an onset Tc of 94 K and a sharp transition, which is almost comparable to the Tc of a single rare earth element 123.
