ABSTRACT:
A precursor is made by mixing a metal alkoxycarboxylate-containing liquid with a 2-ethylhexanoic acid in an effective amount for shelf-stabilizing said liquid by substituting 2-ethylhexanoate ligands for alkoxide ligands, thereby forming a mixture, and heating said mixture to substitute said carboxylate ligands for said alkoxide ligands. Specficially, a barium strontium titanate precursor and a strontium bismuth tantalate precursor are made by combining polyoxyalkylated metal moieties to form a liquid solution in which the metal atoms bond with an oxygen atom in a ligand selected from a ligand group consisting of alkoxides and carboxylates, then then heating the liquid solution.
