화학기상응축 공정에서 TiO 2 나노입자 특성에 미치는 반응온도와 전구체 농도의 영향 - Part I: SMPS를 이용한 실시간 입자특성 평가
Effects of Temperature and Precursor-concentration on Characteristics of TiO 2 Nanoparticles in Chemical Vapor Condensation Process -Part I: Real-time Particle Characterization by SMPS
E-mail:
Properties of nanoparticles synthesized during gas phase reaction were studied in terms of particle behaviors using real-time particle characterization method. For this study, TiO 2 nanoparticles were synthesized in the chemical vapor condensation process(CVC) and their in-situ measurement of particle formation and particle size distribution was performed by scanning mobility particle sizer(SMPS). As a result, particle behaviors in the CVC reactor were affected by both of number concentration and thermal coagulation, simultaneously. Particularly, growth and agglomeration between nanoparticles followed two different ways of dominances from coagulations by increase of number concentration and sintering effect by increased temperature.
