Plasma ways to obtain ultrafine oxides

Abstract

The paper is devoted to a research of the plasma torch application for production of ultrafine materials. The possibility of obtaining a nanosized connection of magnetic ferrite nanoparticles, such as iron oxide Fe₂O₃ is investigated, and also the determination of the experimental parameters of the experimental installation and the experimental conditions. The single-phase low-power alternating current plasma torch was used in the initial stage of the experiments. Plasma torch construction allows the work material to be fed in several points along the plasma flow including directly into the arc chamber. Plasma chemical facility containing the alternating current plasma torch, the feed system of the work material, the plasma chemical reactor and the system of the end product collection is created. Iron(III) nitrate as a precursor is fed into the air plasma jet. The produced iron oxide is investigated by x-ray phase analysis and method of static light diffusion.
