ABSTRACT:
The invention is generally accomplished by mixing non-phosphorous containing metal coordination complexes and phosphorous coordination complexes, forming a coating of the mixture on a substrate and heating the mixture to recover a thin film coating of metal phosphate. The metal coordination complexes and phosphorous coordination complexes are defined as metal-ligand compounds where the ligand is thermally separable. The preferred ligands are carboxylates, alcoholates, and acetylacetonates. The heating decomposes the metal phosphate precursor coating materials to yield a metal phosphate. The phosphorous coordination complex may comprise an alkyl phosphate, arylphosphate, or a carboxylate substituted alkyl or aryl phosphate. The substituting carboxylic acids may be pure, such as 2-ethylhexanoic acid, mixtures of acids, such as neodecanoic acid, and naturally occurring acids, such as rosin (abietic acid). The metal coordination complex may be a metal carboxylate, a carboxylate substituted alkoxide, or carboxylate substituted acetylacetonate. Typical metals are the alkali metals, alkaline earths, titanium, zirconium, and aluminum.
