<p>Provided is a production method by which titanium dioxide particles that are suppressed in quality variation can be obtained. A method for producing titanium dioxide particles, which comprises: a step 1 wherein solid aluminum chloride is liquefied and then gasified, while applying heat and pressure thereto, thereby producing an aluminum chloride gas; and a step 2 wherein a titanium tetrachloride gas is reacted with oxygen and/or water in the presence of the aluminum chloride gas, which has been produced in the step 1. Since the flow rate of the aluminum chloride gas produced in the step 1 can be controlled, titanium dioxide particles that are suppressed in quality variation can be produced in the step 2.</p> |
