The crystals in this group show many interesting features which one might expect in a relatively open structure, in particular phase transitions as a function of pressure and temperature. The description of the dispersion curves by shell models with many adjustable parameters is very unsatisfactory, at least in the oxides, while the fluorides exhibit a

Die Rutilstruktur last sich u.a. als verzerrt, hexagonal dichteste Sauerstoffpackung, ip der die Halfte der Oktaederlucken mit Ti4+-Ionen besetzt ist, diskutieren (Bild 2). Die Oltaeder sind entlang der c-Achse Uber kanten zu Krtten verknupft. In Richtung der a1- und a2-Achse alternieren besetzer und unbesetzte Oktaederketten.

Diffusionsanisotropie im Rutil
1975Zur Untersuchung der Diffusionsanisotropie im Rutil wurden die in Tab. 1 zusammengestellten Experimente durchgefuhrt. An (010)-Anschliffen der Rutilwurfel wurden nach dem Tempern mit der Mikrosonde Diffusionsprofile fur Chrom in a- und c-Richtung des Rutils gemessen. Die Diffusionsprofile der Praparate D1 — D4 sind in Bild 5a — d graphisch dargestellt.

Abstract Sixteen structure types derive from the aristotypic rutile, TiO2, structure. Seven of these are based on an ordering of cations: the CoReO4, MgUO4, AlWO4, CuUO4, trirutile, CuSb2O6 and FeNb2O6 types; three on an ordering of anions: the InOOH, the manganite and HgFOH types; and six more on various distortions from the aristotype:
