Abstract
A precursor solution for the preparation of metal phosphates is provided. Two components are prepared in which the first is a metal salt dissolved in alcohol, and the second component is phosphorous pentoxide dissolved in alcohol. The two components are mixed and may be applied as a liquid coating to a variety of substrates. The coated substrate is then heated, causing removal of all other components and leaving a layer of pure metal phosphate.
Claims8
A precursor solution for preparing metal phosphate said solution comprising a mixture of a metal salt dissolved in alcohol and phosphorous pentoxide dissolved in alcohol.
Method of applying a metal phosphate to a substrate, said method comprising the steps of preparing a precursor solution for a mixture of components comprising a metal salt dissolved in alcohol and phosphorous pentoxide dissolved in alcohol, applying said precursor solution to said substrate to form a metal phosphate.
A method for preparing a precursor solution for the formation of a metal phosphate, said method comprising the steps of preparing a first component comprising the steps of preparing a first component comprising a solution of an alcohol solvent and a metal salt soluble in said alcohol, preparing a second component comprising phosphorous pentoxide dissolved in alcohol wherein said alcohol becomes at least partially esterfied, and then mixing the first and second components together.
