Abstract

Using the Sedimentation method it's possible to get $TiO_2$ particle from which by this research, $TiO_2$ particle was produced. The parameter in the kind of the temperature and the alcohol solvent used $TiO_2$ particle production investigated crystal structure of $TiO_2$ particle and the influence exerted on the size of the particle and the form. After scanning electron microscope (SEM) analyzed methyl alcohol, iso-propylalcohol and tert-butylalcohol used by a solvent at the $TiO_2$ particle production, iso-propylalcohol was most effective. And after an thermogravimetric analyzer method was used, the anatase structure was maintained $500^{\circ}C$ by $200^{\circ}C$, but it was converted by the rutile structure by $800^{\circ}C$.

본 연구에서는 $TiO_2$ 입자를 얻을 수 있는 침전법을 이용하여 $TiO_2$ 입자를 제조하였다. $TiO_2$ 입자 제조시 사용되는 알콜 용매의 종류와 온도 변화 등의 매개변수가 $TiO_2$ 입자의 결정 구조, 입자의 크기 및 형태에 미치는 영향을 조사하였다. $TiO_2$ 입자제조시 용매로 사용한 알콜 종류인 methyl alcohol, iso-propylalcohol, 그리고 tert-butylalcohol를 scanning electron microscope(SEM) 분석한 결과 iso-propylalcohol이 가장 좋은 결과를 가져왔다. 그리고 온도 변화를 열분석법을 사용한 결과 $200^{\circ}C$에서 $500^{\circ}C$까지는 아나타제 구조를 유지하였으나, $800^{\circ}C$에서는 루틸 구조로 전환되었다.
