N2 - Powder alpha-VOSO4 was prepared by dehydration of VOSO4 center dot 3H(2)O. beta-VOSO4 was synthesized by boiling of V2O5 in H2SO4. Thermal behaviour of VOSO4 center dot 3H(2)O, alpha- and beta-VOSO4 modifications is studied by high-temperature powder X-ray diffraction and thermal analysis, including two-step dehydration of VOSO4 center dot 3H(2)O, formation of alpha-VOSO4, thermal expansion and decomposition of both modifications into V2O5. Higher anisotropy of thermal expansion of the tetragonal alpha-modification alpha(c) = 39(2).10(-6) K-1 along the vanadyl ion and alpha(a) = 2.4(6).10(-6) K-1 in the perpendicular direction) comparing to the orthorhombic beta-modification (alpha(a) = 20.2(7), alpha(b) = 2.8(8), alpha(c) = 17.8(4).10(-6) K-1) is explained from a crystal chemical point of view.
