Synthesis of Lithium Transition-Metal Oxide Nanoparticles by Induction Thermal Plasmas

Abstract

Tungsten boride and molybdenum boride nanoparticles were successfully synthesized by induction thermal plasma. The different composition of metal (W or Mo) to boron was changed to investigate the formation mechanism of metal boride nanoparticles. The calculated nucleation temperature clarified that the reactions of MoB system can occur more easily than that of W-B system. The products of W-B system showed greater deviation from the thermodynamic equilibrium phase than MoB system.
