Abstract Subject headings

beta-Al2TiO5 (dialuminium titanium pentaoxide), grown by rapid cooling of a melt of equimolar amounts of Al2O3 and TiO2, adopts the same overall structure as that crystallized by more conventional methods, such as sintering. Nevertheless, reinvestigation of this structure has resulted in an improved structure model with previously unknown site preferences determined. Ti prefers the slightly more regular 4c octahedral site, leaving more room for Al at the 8f octahedral site. The formula has been determined as ([4c])[Al-0.626 ((7)) Ti-0.374 ((7))]([8f])- [Al-0.687 ((3)) Ti-0.313 ((3))](2)O-5.
