Abstract
Abstract Copper alkoxy alkoxides of the formula CuOR or Cu(OR) 2 , where R is derived from an alkoxy alkanol of from 3 to 8 carbon atoms, are superconducting ceramic precursors. Compositions containing these alkoxides solubilized in an organic solvent, such as toluene, can be prepared by the additional use of a barium alkoxide solubilization agent.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
63 words
A composition comprising an organic solvent, a copper alkoxy alkoxide of the formula CuOR or Cu(OR) 2 , where R is alkoxyalkyl having a total carbon content of from about 3 to about 8, suspended or solubilized in the solvent, and an effective amount of a barium alkoxide solubilizing agent for increasing the solubility of the copper alkoxy alkoxide in the organic solvent.
Claim 2
Dependent Claim
