Achievement of Mass Production System of Attractive Nanoparticles by Thermal Plasmas

Abstract

Functional nanoparticle syntheses by thermal plasmas are reviewed. The advantages of thermal plasmas, such as high enthalpy, high chemical reactivity, and rapid quenching capability, have brought the advances and demands in plasma processing. Recent researches by DC arc, multiphase AC arc, and induction thermal plasma are summarized. Metal, intermetallic compounds, oxide, nitride, and boride nanoparticles are successfully synthesized by thermal plasma method. In particular, nanomaterial synthesis for the utilization in lithium-ion battery are summarized. Attractive nanomaterials related to cathode, anode, and electrolyte are successfully synthesized by thermal plasmas. High-productivity of the nanoparticles by thermal plasmas for industrial utilization can be achieved by improving energy efficiency and solving electrode erosion issue.
