Plasma chemical technology for processing rare earth elements in the production of nano-powder

The development and application of a plasma chemical method for producing dispersed materials were considered. A laboratory facility was designed to experimentally investigate the plasma chemical method aimed at producing dispersed oxides of several rare earth metals. The basic physical and chemical properties of synthesized titanium, zirconium, cerium and yttrium oxides were studied. Properties of raw materials and final products were investigated by advanced physical and chemical methods. The factors that influence the composition and quality of produced powders were determined. With increasing concentration of a metal nitrate solution in the range of 20-100 g/L, the average particle size of a powder is found to increase from 0.03 to 1 μm.
