Metal ferrites synthesis by AC plasma torch

Abstract

The article describes the ac air plasma torch with the supply of a liquid aqueous solution of iron (III) nitrate of (mol/l). When the solution is heated, water evaporates, and the iron nitrate is converted to a solid residue (mainly iron oxide). The obtained samples were collected on a heated filter to prevent condensation of water and nitrogen dioxide. The obtained samples were investigated by the X-ray diffractometer and the scanning election microscope with an elemental analyser. The proposed plasma method can be applied to the synthesis of ferrites of various metals.
