High-frequency induction thermal plasma has the characteristics of high energy density, high temperature and fast cooling rate, and is one of the important means to prepare special powders. Yuan Fangli and others from the Institute of Process Engineering, Chinese Academy of Sciences used the high temperature and rapid cooling process of thermal plasma, and the coarse particles were gasified by the plasma arc at high temperature. , cobalt and nickel powder, nano silicon powder can be used as negative electrode material for lithium ion battery. Irregular particles with a fixed melting point are melted in the plasma arc to form spherical droplets, and regular and dense spherical particles can be obtained by rapid cooling. spherical powder. Utilizing the instantaneous enhanced reduction reaction of active hydrogen and chemical vapor deposition, spherical metal ultrafine powders such as ultrafine tungsten, molybdenum, nickel and copper can be prepared. Active oxygen helps to regulate the oxidative growth process of particles, and various oxides with special morphologies can be obtained by the oxidation reaction of metals.
