Title: Improvements in and relating to the production of substantially pure thorium and uranium and binary and ternary alloys of thorium, uranium and zirconium
IPC: C01B7/14
Filed: 1958-08-05
Abstract: In the production of thorium or uranium by reacting a carbide of the metal with iodine and decomposing the iodide, the raw material, e.g. oxide, is converted into the carbide by reaction with carbon at high temperature.  Thorium oxide may be mixed with pure carbon, such as graphite or sugar charcoal, and the mixture, with an organic binder, pressed to compact masses and heated for at least 30 minutes in a carbon tube resistor furnace to a temperature above 2100 DEG C. in an oxygen-free atmosphere.  The carbide compacts are cooled in the inert atmosphere, crushed in an atmosphere of dry argon or nitrogen and transferred to a bulb which is evacuated, e.g. to 10-5 m.m. of mercury.  The bulb contains also iodine, previously dried by multiple distillation in p  vacuo, in amount of 2 parts by weight of iodine to 20 parts by weight of carbide.  The bulb is heated to above 400 DEG C, e.g. 485 DEG C. to evaporate the iodine for reaction with the carbide to form a volatile thorium iodide which is decomposed on a heated filament within the bulb.ALSO:A process for the production of metallic uranium or thorium from a crude source, comprises converting the raw material, if other than carbide, into carbide of the metal, reacting the carbide with iodine to form a volatile iodide, decomposing the iodide to liberate the metal and reacting the liberated iodine with further carbide.  The process may also be applied in the production of binary or tetnary alloys of metals selected from thorium, uranium and zirconium by treatment of mixed carbides. The carbide, preferably in the form of crushed pellets is placed in a sealed bulb or container which is evacuated to a pressure below 10-4 m.m. of mercury and which contains dry iodine. The bulb is heated to at least 400 DEG C. and a filament in the bulb is heated to 1100-1400 DEG C.  The iodine reacts with the carbide to form volatile halide which is decomposed to deposit the metal on the hot wire and to liberate iodine for reaction with further carbide.
