Metallurgy and superconductivity in Ce-doped and Ce-Ti-doped Nb/sub 3/Sn samples were investigated. The wires containing Ce-bronze and Ce-Ti-Bronze were not noticeably difficult to draw. The addition of Ce to the bronze not only enhances the growth rate of the Nb/sub 3/Sn layer but also improves the composition distribution within the wire. The critical temperature T/sub c/ of Ce-doped samples treated at 700/sup 0/C are obviously higher than pure Nb/sub 3/Sn. The J/sub c/ difference between samples with small amount of Ce and pure Nb/sub 3/Sn is not obvious. J/sub c/ decreases slightly in low-field with increasing Ce content.
