WebRecent studies in ultrahigh vacuum (UHV) have revealed a wealth of information on well-defined anatase surfaces (18–24), yet their structures and properties, such as bonding … WebAnatase is a metastable mineral form of titanium dioxide (TiO 2) with a tetragonal crystal structure. Although colorless or white when pure, anatase in nature is usually a black solid due to impurities. Three other polymorphs (or mineral forms) of titanium dioxide are known to occur naturally: brookite, akaogiite, and rutile, with rutile being the most common and …
