Abstract

Ultrafine particles have been widely used in many high technology industrial areas. The spherical nonagglomerated and uniform nanometer-size $SiO_{2}$ particles are synthesized by the injection of TEOS vapor, ions and reaction gas in furnace. Ions were generated by Corona discharge electrode and these ions charge $SiO_{2}$ particles. As a result, spherical, nonagglomerated and ultrafine particles are generated in various conditions, it's morphology, charging portion and size distribution are examined by using TEM, ESP and SMPS. As the applied voltage of electrode changes from 0 kV to 5.0 kV, it is observed that the mean diameter of $SiO_{2}$ particle decreases from 94 nm to 42 nm.
