ABSTRACT:
Novel metal acid salt complexes are provided comprising (1) a metal selected from Group IV and Group V metals and (2) a polyether acid, along with a process for making the salt complexes. The process comprises: (a) preparing a polyether acid anhydride from the corresponding polyether acid; and (b) combining a metal alkoxide containing the Group IV or Group V metal with the polyether acid anhydride to form the metal acid salt complex. The resulting Group IV and Group V metal acid salt complexes enable the production of improved thin film, thick film, and bulk ceramic metal oxides and mixed metal oxides for a number of applications, including ferroelectric, electrooptic, paraelectric, and piezoelectric devices, using liquid soluble precursors which are soluble in far less toxic solvents than in the prior art. The soluble ceramic precursors may also be used as reactive binders and shape-forming aids in conventional ceramic processing.
