Abstract
Particulates, particularly ultrafine particulates of titanium oxide having a BET specific surface area of from about 3 m /g to about 200 m /g, preferably from about 5 m /g to about 200 m /g, and more preferably from about 10 m /g to about 200 m /g are obtained using a vapor phase process of producing titanium oxide by oxidizing titanium tetrachloride with an oxidizing gas at a high temperature, wherein a titanium tetrachloride-containing gas and an oxidizing gas are reacted after preheating each gas at about 500° C. or more. The particulates, particularly ultrafine particulates of titanium oxide have less aggregation and have highly excellent dispersibility.
