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.
Claims7
A sprayable inorganic-organic phosphate ceramic precursor system comprising:
- an aqueous-based slurry or a suspension, separately comprising components (a) and (b) as follows:
- (a) at least one inorganic phosphate 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;
- and
- (b) at least one basic oxide or hydroxide of formula B2mOm or B(OH)2m, where B is a 2m-valent metal;
- and m=1 or 1.5;
- and
- at least one organic phase precursor present at a weight percent of 2 to 50 in (a) or (b), or (a) and (b), wherein the at least one organic phase precursor is the product of a reaction with the at least one inorganic phosphate or the at least one basic oxide or hydroxide.
