TiCl4와 반응매개체인 염산수용액을 이용하여 나노크기의 루틸상 TiO2 분말제조
Synthesis of Nanosized Rutile-type Titanium Dioxide Powder from TiCl4 and Hydrochloric Acid used as Reaction Medium
In preparation of TiO2 from aqueous TiCl4 solution by precipitation HCl concentration of the solution and reaction temperature were important factor in determining the structure of TiO2 was precipitates and pure rutile TiO2 was obtained by proper control of these factors. This reaction through which TiO2 was formed from aqueous TiCl4 solution was not precipitation by change of the solubility but crystallization froming TiO2 precipitates at the stage of precipitation.
