- $YBa_{2}Cu_{3}O_{7-δ}$ (YBCO) bulk single-grain superconductors were prepared by a TSMG process. $CeO_{2}$, $BaCeO_{3}$ and $BaO_{2}$ powders were added to nominal composition $Y_{1.5}Ba_{2}Cu_{3}O_{7}$ with the aim to refine $Y_{2}BaCuO_{5}$ (Y-211) secondary particles. Added powders were refined by milling in a friction milling and characterized by X-ray powder difractometry. Thermal properties of the systems were characterized by DTA. Microstructure of samples was studied by PLM. Successful refinement of Y-211 particles size was confirmed by IP measurements. Transition temperatures and field dependences of the magnetic moment for further determination of the critical current densities were obtained using a VSM.
