ABSTRACT:
The invention relates to volatile mixed metal alkoxides of the formula M'.sub.x M.sub.y Cu.sub.z (OR).sub.x+2(y+z) 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 CMe.sub.3, CMe.sub.2 Et, CMeEt.sub.2, CMe.sub.2 Pr, CMeEtPr, CEt.sub.3 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.
