Ri. Bickley et al., RELATIVE PROPORTIONS OF RUTILE AND PSEUDO-BROOKITE PHASES IN THE FE(III)-TIO2 SYSTEM AT ELEVATED-TEMPERATURE, Materials chemistry and physics, 51(1), 1997, pp. 47-53
The Fe(III)-TiO2, system has been studied at T greater than or equal t
o 1023 K in the range of concentration 2-10 at.% of iron by powder X-r
ay diffraction, transmission and scanning electron microscopy, and opt
ical microscopy. The relationship between the relative proportions of
the TiO2, rutile phase and the pseudo-brookite phase Fe2TiO5, has been
investigated in powder samples. Single crystals of pure rutile and ru
tile doped with 0.5 at.% of iron have been examined to elucidate the m
icrostructures found in the powders. The results suggest that a low de
gree of solid solubility exists and that doped crystals contain planar
faults on {101} planes. (C) 1997 Elsevier Science S.A.
