| description | PROBLEM TO BE SOLVED: To provide a method of manufacturing α type titanium hydrogen phosphate monohydrate under a mild reaction condition under ordinary pressure without by-production nor contamination of tabular particles, amorphous powder, titanium dioxide and the like.SOLUTION: There is provided a method of manufacturing α type titanium hydrogen phosphate monohydrate spherical type porous particles including adding hydrous titanium oxide with a molar ratio of PO/TiOin a range of 0.9 to 2.5 under ambient pressure into a phosphoric acid solution having the concentration of 50 wt.% or more at a temperature of 50°C or higher over 0.5 to 12 hours with stirring, keeping the temperature of the phosphoric acid solution at 50°C or higher during the period and aging the resulting reaction mixture under ambient pressure at 70°C or higher for 0.5 to 12 hours after completion of addition of hydrous titanium oxide. |
