FIELD: production of titanium dioxide. SUBSTANCE: plasma of oxygen or oxygen-containing gas is prepared and mixed with liquid titanium tetrachloride, ratio of oxygen and titanium tetrachloride being 1.05-1.2 respectively. Temperature of plasma is 2500-3000 C. Thus prepared product having decomposition temperature 1100-1500 C is hardened to temperature being 0.7 of this value. Then this product is cooled in heat exchanger. EFFECT: improves efficiency of method. 1 dwg, 1 tbl
