  • Patent number: 5421857
    Abstract: In this method for obtaining metals, their compounds, and alloys from mineral raw materials a burden is prepared by mixing a comminuted raw material with additions of chemical elements taken from the chemical composition of the starting raw material, oxidizing roasting is then carried out accompanied by evacuating and utilizing gaseous oxides, and a reduction process proceeds followed by separation of metals and their compounds. According to the invention, in the course of preparing the burden compounds of the above chemical elements containing oxygen are added to the mixture at a ratio of the compounds to the chemical elements ranging from 1:1 to 1:100 and at a total quantity of additions in the burden at least 5%. The oxidizing roasting process proceeds in an oxygen-containing atmosphere at a temperature from 1400.degree. to 1600.degree. C. followed by cooling and comminuting solid oxides obtained.

  • Patent number: 5141776
    Abstract: The method relates to inorganic chemistry.Pursuant to the method, a powder mixture comprising a transition metal, a nonmetal, an inert filler and an activator is prepared; a workpiece to be coated is embedded in the powder mixture and this is placed, integrally with the workpiece, into an oxygen-free medium for a subsequent heat treatment which is accomplished by a locally-initiated combustion of the powder mixture.
