In-flight treatment of rutile TiO_2 particle by using a DC-RF hybrid plasma flow is investigated in this paper. The main objective of this study is to clarify the correlation between the products property and the operating conditions for particle size conversion from micro size to nano size. In a plasma core region, processes are taken place such as evaporation, reduction, nucleation, agglomeration and sintering for a moment One of the most important parameters to decrease the size of products is operating pressure. Mean particle diameter increases and conversion ratio to 100nm size particles decreases with increasing operating pressure because nuclei grow by long particle residence time and large particle heating.
