Abstract

Nanocrystalline vanadium diboride (VB₂) were successfully synthesized at 650 °C through a solid state reaction. The synthesis was carried out by reacting VCl₄ with NaBH₄ and Mg in an autoclave. The X-ray powder diffraction pattern indicates the formation of hexagonal VB₂. An atomic ratio of B to V of 2.11:1.0 is determined from X-ray photoelectron spectra. Transmission electron microscopy image shows that typical VB₂ crystallites are composed of uniform particles with the grain size in the range of 50-100 nm.
