Formation of Niobium Diboride Nanoparticles by the Reaction of Niobium Pentachloride with Sodium Borohydride in Ionic Melts of Alkali Metal Halides

Near-spherical niobium diboride nanoparticles with an average diameter of ~17 nm, crystallizing in the hexagonal system and belonging to the space group P 6/ mmm , were obtained by reacting NbCl 5 with NaBH 4 in ionic melts of alkali metal halides at 1073 K under an argon pressure of 4 MPa for 15 h...

Description
Summary:Near-spherical niobium diboride nanoparticles with an average diameter of ~17 nm, crystallizing in the hexagonal system and belonging to the space group P 6/ mmm , were obtained by reacting NbCl 5 with NaBH 4 in ionic melts of alkali metal halides at 1073 K under an argon pressure of 4 MPa for 15 h in an autoclave.
