ABSTRACT:
A novel method for forming a dispersable, fine titanium pyrophosphate powder by reacting titanium dioxide and a molar excess of phosphoric acid. The excess phosphoric acid, at a phosphorus pentoxide to titanium dioxide mole ratio greater than one, significantly improves the yield of the reaction product as a fine powder. A phosphorus pentoxide to titanium dioxide mole ratio of about 1.20 to about 1.25 results in over a 90% yield of a dispersable, fine titanium pyrophosphate powder having a particle size less than one micron in diameter.
