Abstract
In this paper, the transition metal oxoborate warwickite (Fe2+,Mg)Fe3+(BO3)O is studied for the first time by low- and high-temperature X-ray diffraction in the temperature range from 93 to 513 K. The sharply anisotropic nature of its thermal expansion is revealed. A structural interpretation of the expansion mechanism is given both in terms of the contribution of cationic and oxocentered polyhedra.
