Abstract

The transformation of lithiophorite during thermal treatment has been studied by single crystal x-ray diffraction methods. Lithiophorite was found to transform at 550°C into a spinel phase of γ-Fe2O3 or γ-Al2O3 type structure and the orientational relationships between the two phases have been established. The mechanism of transformation has been explained from a structural view-point by the migration of cations through the lattice. It was found that the [010], [100] and c* directions of lithiophorite became respectively the [1[unk]0], [11[unk]] and [111] directions of the transformed phase.
