Titanium substitution mechanisms in forsterite

Berry, Andrew John; Walker, Andrew; Hermann, Joerg; O'Neill, Hugh; Foran, Garry J; Gale, Julian D

Description

Ti K-edge X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) spectra, together with atomic scale calculations, indicate that Ti occupies the Si site in anhydrous forsterite. The energy and intensity of the 1s → 3d transition in the XANES spectrum is diagnostic of Ti on a four-coordinate site. The EXAFS spectra determine a Ti-O bond length of 1.81 ± 0.01 Å. This value is in excellent agreement with that of 1.8 Å determined computationally by...[Show more]
