Mechanochemically activated synthesis of zirconium carbide nanoparticles at room temperature: A simple route to prepare nanoparticles of transition metal carbides

Mechanically activated syntheses of zirconium carbides (ZrC x ) nanoparticles have been performed via ball milling of Zr powder with toluene. It has been found that the milling time can be used to tune the ratio x of C to Zr. The spark plasma sintering of the ZrC x nanoparticles has shown that the d...

Description
Summary:Mechanically activated syntheses of zirconium carbides (ZrC x ) nanoparticles have been performed via ball milling of Zr powder with toluene. It has been found that the milling time can be used to tune the ratio x of C to Zr. The spark plasma sintering of the ZrC x nanoparticles has shown that the densification can be achieved at a considerably reduced temperature of 1200 °C. This ball milling procedure has been tried to successfully synthesize the nanoparticles of WC x , TiC x , and NbC x , demonstrating that it is a potential route to prepare the nanoparticles of transition metal carbides.
