Hydrothermal synthesis and characterization of V2O3

V2O3 with spherical particles was hydrothermally synthesized (240 °C, 48 h, autogenous pressure) as a single-phase material from a mixture of V2O5, 1,6-diaminohexane and H2O in the mol ratio 1:1:269. It was characterized by scanning electronic microscopy, X-ray powder diffraction, thermal analysis and electron paramagnetic resonance.
