Rutile 상의 TiO2 나노분말 합성 및 물성 분석 = Physical Properties and Synthesis for Rutile Phase TiO2 Nanopowder

다국어 초록 (Multilingual Abstract)

Rutile phase TiO2 nanocrystals were synthesized by using only a hydrolysis reaction and dry
process. To exclude the effects of an exothermic reaction during hydrolysis, we performed the process at low temperature, nearly 0 C. The powder, which had been synthesized only by mixing and stirring, was heat treated at several temperatures from 100 C to 1000 C. The structure and the morphology were investigated through the X-ray diraction and scanning electron microscop,
respectively. Although the temperatures of heat treatment were different, the structures of all
powders had the same rutile phase. The particles were agglutinated in the powders which had been heat treated from 100 C to 600 C and the grain sizes were measured in the powders annealed above 800 C. Finally, we show that rutile TiO2, annealed at 100 C has thermodynamically stable
state and that the diameters and the length of nano-particles are in the ranges of 5 ~10 nm and 45~80nm, respectively.
