Alternative technology for production of pure metals and hard alloys

An ecologically safe technology for the production of pure metals and hard alloys is based on the conversion of oxides in the atmosphere with ultra-low oxidation potential (P_o2 = 10^-21÷10^-28atm) is considered in the paper. The formation of such a medium can be reached by means of oxigen pump. However simplicity and acceleration of the super deep refraction process in oxigen is done with initiation of chemical reaction of combustion of easy dissociated substances, such as alcohols, by their injection into closed contour of reactor. The drop of partial oxygen pressure (up to 10^-28 atm) provides thermic dissociation of practically any oxide. An installation for conversion processes was contsructed and methods for conducting the experiments were worked out. Complete thermodynamic analysis of typical reducing process of oxides with ethyl alcohol in the temperature range 300-1500 K was presented. Pure metals - Cu, Fe, Ni, Co, Carbides, Ti, Cr and hard solutions on the basis of tungsten carbide were obtained. The results of X-ray structure analysis are given. (author)
