Abstract
Titanium dioxide having a ratio D/Dof 1 to 3, between the maximum particle diameter Dand the average particle diameter D, as determined based on observing the primary particles by a field emission-type scanning electron microscope. A production process of the titanium dioxide comprises performing a vapor phase process of reacting a titanium tetrachloride-containing gas with an oxidative gas to produce titanium dioxide, wherein when the titanium tetrachloride-containing gas and the oxidative gas are reacted by introducing each gas into a reaction tube, the temperature in the reaction tube is from 1,050 to less than 1,300° C.
