More Information
Summary:The invention discloses a polyhedral titanium pyrophosphate powder and a preparation method thereof, belonging to the technical field of titanium pyrophosphate. The titanium pyrophosphate powder in the invention is of a cubic angle-cut polyhedron structure with a polygon cross section and a particle diameter of 100-1200 nm. The preparation method in the invention comprises the following steps: dissolving a titanium source into an anhydrous alcohol solvent to obtain a titanium-alcohol solution; dropwise adding an alcohol-water mixture into the titanium-alcohol solution at a constant rate for reaction to obtain a suspension A; dropwise adding a phosphorus source aqueous solution into the suspension A for reaction till the system is clear to get a clear liquid B; volatilizing the solvent in the clear liquid B to obtain a gel C; and heating the gel C as a precursor to reach a roasting temperature at a constant rate for roasting at a high temperature, cooling within the oven, washing with water and drying to obtai
