The purpose of this work is to show a possibility of receiving electrolytic nickel-containing powders of the predicted structure at anode dissolution of secondary heat resisting alloys.
The paper presents the results of the synthesis of the xerogel of vanadium in the interaction of vanadium pentoxide and ammonium. It is shown that as a source of vanadium pentoxide can be used successfully vanadium carbonaceous – siliceous shales. Using obtained vanadate ammonium in receiving technology of vanadium xerogel is more cost effective process than the use for this purpose the chemical reagent. Integrated use of this unique raw material is a critical component of modern waste-free and environmentally friendly technologies to highlight not only the connection of valuable components, but also the raw material for the production of vanadium xerogels.
Synthesized by sol-gel method based on vanadium oxide xerogels with partially ordered highly layered structures already are widely used in various fields of science and technology due to their unique properties. Scope xerogels vanadium: production photocatalysts, composites, membranes and ion exchange materials.
