용매열합성을 이용한 구형 $TiO_2-SiO_2$ 복합체 제조 및 열적특성 = A Synthesis of Spherical Shape $TiO_2-SiO_2$ Complex via Solvothermal Process and Thermal Properties at Non-Isothermal

다국어 초록 (Multilingual Abstract)

Nanomaterial $TiO_2-SiO_2$ was synthesized by hydrolysis and condensation process using 2-propanol(2-PrOH) and was characterized by FT-IR, DSC, XRD and FE-SEM. FT-IR spectra were measured to investigate Ti-0-Si absorption peak. DSC thermal analysis results appllied to Ozawa equation were used to calculate to activation energy of crystallization. It was found that the changes of X-ray diffraction patterns and FWHM obtained XRD measurement depended on calcination temperature. In FE-SEM analysis, particle size changed by quantity changes of Ti-alkokide.
