Topotaxy in the Anatase-rutile Transformation


Lhe anatase-rutile transformation has been shown to result in preferred orientation of the product but with no preservation of the anatase axes of symmetry. It is, therefore, classified as a case of intermediate toootaxv. planes. A cooperative movement of the titanium and oxygen ions is proposed in which the majority of the titanium ions, in order to reach their new sites, break onlv trvo of their original six Ti-O bonds.
