The invention relates to volatile mixed metal alkoxides of the formula MXMYCuz OR x2yz wherein M is selected from the group consisting of Ba, Sr, and Ca, M is an alkali metal, x 0-6, y 0- 4 and z 1 to 6, and x and y are not 0 at the same time, and R is selected from the group consisting of Cme3, CMe2Et, CMeEt2, CMe2Pr, CMeEtPr, CEt3 or combinations of these substituents. Volatile alkoxides of Y and Cu are known. These volatile alkoxides can be used in a CVD process where stoichiometric quantities of the material are sublimated, transported to a substrate and decomposed to an oxide with or without the presence of oxygen. The oxides are then treated in a known manner to produce the superconducting film. Patent applications.
