Abstract
This disclosure relates to an inorganic-organic metal phosphate ceramic coating from the reaction of an inorganic phosphate of the formulas (i) Am(H2PO4)m·nH2O or (ii) AH3(PO4)2·nH2O; where A is ammonium or an m-valent metal element; m=1, 2, or 3; and n is 0 to 25; and at least one metal oxide or hydroxide represented by the formula B2mOm or B(OH)2m, where B is a 2m-valent metal; and m=1 or 1.5; thereof; and at least one polymer capable of reacting with at least the one metal oxide or hydroxide; or a first organic precursor combined with the inorganic phosphate and a second organic precursor combined with the at least one metal oxide or hydroxide, the second organic precursor configured to chemically react with the one or more first organic precursor.
Claims15
An inorganic-organic phosphate ceramic precursor system comprising:
- a first part comprising:
- (a) at least one inorganic phosphate salt representative of one or more of formula (i), Am(H2PO4)m·nH2O or (ii) AH3(PO4)2·nH2O;
- where A is an m-valent metal element;
- m=1, 2, or 3;
- and n is 0 to 25 or phosphoric acid;
- and water;
- and a second part combinable with the first part, the second part comprising:
- (b) at least one basic oxide or hydroxide represented by the formula B2mOm or B(OH)2m, where B is a 2m-valent metal;
- and m=1 or 1.5;
- and water;
- wherein at least one of part (a) and part (b) comprise a polymer.
