Abstract

Solubilized metal (dialkylaminoalcoholate) compounds in organic solvent can serve as a source of metal values for metal oxide-containing superconductor compositions. Stable solutions, resistant to precipitation problems, can be formed by reaction of a dialkylaminoalkanol with a metal alkoxide followed by removal of by-product alkanol by vacuum distillation below the reflux temperature of the solution. Exemplary metals include copper, yttrium, barium, calcium, and bismuth, lanthanum and strontium.
