Abstract

The experimental investigation of the gas-phase synthesis of the nanosized particles of titanium dioxide (titania, TiO2) from gaseous titanium tetrachloride (TiCl4) in the plasma chemical flow reactor is carried out. The processes of formation and growth of particles, formation of their agglomerates in combined reaction and quenching zones are considered. The conducted experiments reveal that using this technique it is possible to produce ultrafine powder (with particle mean size less than 30 nm) providing the required content of the metastable crystal lattice – 80-87% anatase (A). The content of rutile (R) crystal lattice in the powder doesn’t exceed 15-20%. The experimental data are found to agree satisfactorily with the results of simultaneously performed numerical simulations.
