摘要： High-purity metallic chromium is produced by a method of initially preparing a mixture of chromium oxide, aluminum, carbon and an easily sulfidable metallic powder, and subsequently providing a thermite-reaction with the mixture to produce thermite-crude metallic chromium and a solid solution of carbon and easily sulfidable metal. Residual impurities in the thermite-crude metallic chromium are subsequently removed by heat treating the crude metallic chromium. This method produces high-purity metallic chromium advantageous for preparing corrosion and heat resistant chromium-containing alloys.

摘要： A method for producing metal by the reduction of a metal halide by a reducing metal agent capable of continuously producing homogeneous metal of high purity. In the method, particles of the same metal as the metal to be produced are charged into a reaction vessel and the metal halide and the reducing metal agent both in vapor form, are ejected upwards into the reaction vessel from its lower portion to form a fluidized bed of the metal particles in the vessel. The reducing reaction between the two vapors takes place on the surface of the metal particles at a temperature below the melting point of the metal product and at a pressure below a vapor pressure of each of the reducing metal agent and the metal halide at that temperature, resulting in depositing and growing the metal product on the surface of the particles.

摘要： Apparatus for producing low cost, high purity solar grade Si wherein a reduction reaction, preferably the reduction of SiF.sub.4, by an alkali metal (Na preferred) is carried out by jetting a spray of reactants into a reaction chamber at a rate and temperature which causes the reaction to take place far enough away from the entry region to avoid plugging of reactants at the entry region and wherein separation in the melt is carried out continuously from the reaction and the Si can be cast directly from the melt. The melt separation is provided by openings in the reaction chamber wall between about 2 to about 3.5 millimeters in width. The Si is retained within the reaction chamber due to its surface tension.
