| Abstract: | The formation of TiO2 powders by oxygenolysis of TiCI4 was studied with emphasis on the effects of reaction conditions on the particle size of the products. The particle size of TiO2(anatase) decreased with increasing reaction temperature or O2concentration and with decreasing TiCI4 concentration. The results are compared with those for the oxygenolysis of AlBr3and SiCI4. It was found that the reactivity of metal halides with O2 is closely related to the ease of dissociation of the first halogen atom. |
