Anatase and rutile are crystalline forms of titanium dioxide, differing primarily in structure and physical properties. Anatase has a tetragonal structure, making it less dense and providing a higher surface area, beneficial for photocatalytic activities. Rutile, with its more compact tetragonal structure, is denser and considered ...

The ilmenite is converted to rutile if the titanium dioxide content is high enough and most of the iron can be smelted out. From there, some purer rutile is refined into pure white titanium dioxide through a chlorination process, producing titanium chloride (TiCl 4). That is then heated with oxygen to form the crystalline, pure white titanium ...
