Anatase and another polymorph, brookite (orthorhombic), are converted to rutile (tetragonal) by heating above 700 C. Pattern reviewed by Holzer, J., McCarthy, G., North Dakota State Univ, Fargo, North Dakota, USA, ICDD Grant-in-Aid (1990). Agrees well with experimental and calculated patterns. Validated by calculated pattern. Pattern taken at 25 C. 2-Theta d(?)
