Superconducting films in the Bi--Sr--Ca--Cu--O systems were made using metal alkoxides. To prepare a dip-coating solution using a mixed alkoxide solution, insoluble Cu and Bi alkoxides were dissolved by modification with 2-dimethylaminoethanol and formation of a double alkoxide, respectively. Formation of the double alkoxides of Bi with Ca or Sr was confirmed using FT-IR and {sup 1}H-NMR. Bi--Sr--Ca--Cu--O films on yttria-stabilized ZrO{sub 2} and single crystal MgO(100) substrates were made using this solution. The films were closely oriented along the {ital c}-axis perpendicular to the substrate. The film on MgO(100) fired at 850 {degree}C for 48 h showed two resistance drops around 115 and 85 K, corresponding to the high-{ital T}{sub {ital c}} and low-{ital T}{sub {ital c}} phases, respectively, and zero resistance at 72 K.
