  • Alcohol-based precursor solutions for producing metal phosphate materials and coating
    Patent number: 6036762
    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.
