β¦ Synopsis
The crystal structure of anosovite, (Ti 1.69 Al 0.26 Fe 0.05 ) 3+ (Ti 0.97 Zr 0.03 ) 4+ O 5 , prepared by carbothermal reduction of leucoxene under vacuum at 1450Β°C has been refined by Rietveld method using powder X-ray diffraction data. It was found that it represents slightly monoclinically deformed pseudobrookite type structure with lattice parameters a = 9.8111 Γ , b = 3.7509 Γ , c = 9.9468 Γ , Ξ² = 90.628Β°.
