METHOD FOR MANUFACTURING AN ANATASE TYPE TITANIUM DIOXIDE NANO PARTICLE HAVING A UNIFORM PARTICLE AND EXCELLENT CRYSTALLINE PROPERTIES

摘要

PURPOSE: A method for manufacturing an anatase type titanium dioxide nano particle is provided to massively manufacture a anatase type titanium dioxide nano particle having excellent crystalline through a simple process without a separate thermal process.;CONSTITUTION: A method for manufacturing an anatase type titanium dioxide nano particle comprises the following steps: a step of uniformly mixing titanium t-butoxide and cetyltrimethyl ammonium chloride or cetyltrimethyl ammonium bromide with water; a step of hydrothermal-treating the mixture at 60~120°C; a step of obtaining a titanium dioxide nano particle, which is generated through the hydrothermal treatment, and drying the titanium dioxide nano particle; and an additional step for plasticizing the obtained titanium dioxide nano particle before or after drying the titanium dioxide nano particle. A molar ratio of titanium t-butoxide and cetyltrimethyl ammonium chloride or cetyltrimethylammonium bromide is 4:0.5 ~ 4:2, respectively.;COPYRIGHT KIPO 2010
