Volatile Divalent Double Metal Alkoxides.
Abstract
The invention relates to volatile mixed metal alkoxides of the formula M'(X)M(Y)Cu(z) (OR) 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 Cme3, CMe(2)Et, CMeEt(2), CMe(2)Pr, CMeEtPr, CEt(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. Patent applications.
