Characteristics of nanostructured TiO2 powders synthesized by combustion flame-chemical vapor condensation process

Abstract

Combustion Flame-Chemical Vapor Condensation(CF-CVC) process which can continuously produce nanostructured powders has been used to produce non-agglomerated TiO2 powder. The synthesized powders are characterized for crystal structure, chemical composition, and particle size by using HRTEM, X-ray, TG-DTA, and SIMS. Nanostructured TiO2 powders have mixed state of mostly anatase phase and small amount of rutile phase with particle size of about 20nm and 60 similar to 70nm, respectively.
