Short summary
Paramontroseite is a V dioxide (a = 4.8960(14) Å, b = 9.395(3) Å, c = 2.9163(5) Å, V = 134.14(6) Å3; space group Pbnm). The sample under investigation (Prachovice mine, Czech Republic) bears 20 wt % of Fe2O3, and the Fe atoms occupy tetrahedral sites arranged in the empty channel along z. Thermal expansion is anisotropic. At T > 350 °C, paramontroseite decomposes and two new phases form: V2O5 (V-pentoxide) and V4Fe2O13 (Fe-tetrapolyvanadate).
