摘要：
Near-spherical niobium diboride nanoparticles with an average diameter of similar to 17 nm, crystallizing in the hexagonal system and belonging to the space group P6/mmm, were obtained by reacting NbCl5 with NaBH4 in ionic melts of alkali metal halides at 1073 K under an argon pressure of 4 MPa for 15 h in an autoclave.
