Anatase is one of the three mineral forms of titanium dioxide, the other two being brookite and rutile. It is always found as small, isolated and sharply developed crystals, and like rutile, a more commonly occurring modification of titanium dioxide, it crystallizes in the tetragonal system; but, although the degree of symmetry is the same for both, there is no relation between the interfacial angles of the two minerals, except in the prism-zone of 45A and 90A . Due to its functionality as a semiconductor oxide photocatalyst and its considerable interest towards GrA tzel-cell photovoltaics, a majority of studies into anatase materials have focused on synthetic materials in powder and thin film forms rather than naturally occurring minerals. Crystalline anatase can be prepared in laboratories by chemical methods such as sol-gel method. Examples include controlled hydrolysis of titanium tetrachloride (TiCl4) or titanium alkoxides. Often dopants are included in such synthesis processes to control the morphology, electronic structure and surface chemistry of anatase.
