| titleOfInvention | Production Method of Nano-sized Crystalline Titania Powders |
| abstract | The present invention relates to a method for producing titanium dioxide nanoparticles, and to provide a method for producing titanium dioxide nanoparticles having excellent particle size distribution and crystallinity and excellent optical properties.n n n In the method for preparing titanium dioxide nanoparticles of the present invention, a precursor of titanium tetraisopropoxide (TTIP) is added to the ultrapure water to hydrate the reaction (A-1) and (A-1). The precipitate is filtered, washed with ultrapure water to remove impurities, and then dried to prepare amorphous titanium dioxide powder (A-2), and amorphous titanium dioxide particles and Tio 2 / prepared in (A-2). The step (B) of reacting the HNO 3 molar ratio with 1.0 / 0.5 to 1.0 / 2.0 peptizing agent in a high pressure reactor at 100 to 120 ° C. to form a titanium dioxide sol, and heating the temperature to 150 to 300 ° C. in a high pressure reactor, the vapor pressure to 150 Pressurizing to atmospheric pressure to grow the titanium dioxide sol into titanium dioxide particles (C-1), centrifuging the titanium dioxide crystals, adjusting the pH to neutral (pH 6-8) with NaOH, then centrifuging again and then ultrapure water Washing with a powder (C-2) and (C-2) Dispersing the powder obtained in the step in ethanol and drying (C-3). |
