TiO₂ nanoparticles were synthesized from titanium tetraethoxide (TEOT) dissolved in ethanol using a semibatch-batch two-stage mixed method. In this work, a statistical experimental method was used to compare various properties of TiO₂ particles according to six parameters [concentration of TEOT during 1^st and 2^nd stages, reaction temperature during 1^st and 2^nd stages, and amount of hydroxypropyl cellulose (HPC) during 1^st and 2^nd stages]. It was found that the optimal conditions for the preparation of TiO₂ nanoparticles using this method were as follows; (1^st TEOT (M): 0.08~0.10, 2^nd TEOT (M): 0.13~0.15, 1^st Temp. (℃): 15~20, 2^nd Temp. (℃): 35~40, 1^st HPC ((X10^-2 g/cc): 0.015~0.019, 2^nd HPC ((X10^-2 g/cc): 0.25~0.30). The experimental results using the above optimal conditions were in agreement with the theoretical data and produced the smallest size (~30 nm in diameter). In addition, it was found that the main parameters affecting the preparation of TiO₂ nanoparticles were the concentration of TEOT and reaction temperature during the second stage.
