ABSTRACT:
A water-stable and water-soluble ceramic precursor is provided, containing at least one Group III element. Also, a metal acid salt complex is provided comprising (1) bismuth, lanthanum, and titanium, and (2) a polyether acid. In addition, methods are provided for preparing the Group III metal acid salt complex and the Bi, La, Ti acid salt complex comprising a bismuth polyether acid salt complex, a lanthanum polyether acid salt complex, and a titanium polyether acid salt complex. Finally, devices that include lanthanum-doped bismuth titanate as the active component are provided, as well as a water-stable and water-soluble gallium polyether acid complex.
