摘要
Vanadium monoxide, VO (y) has been studied within its homogeneity range using X-ray diffraction and pycnometric density measurements. The density and lattice parameter of VO (y) have been shown to vary in a complex manner with oxygen content near the stoichiometric composition VO1.0. The experimental data have been used to evaluate the vanadium and oxygen vacancy contents in VO (y) . We assume that two cubic phases close in lattice parameter coexist near the composition VO1.0 and form a solid solution.
