The amalgam-metallurgical process for obtaining uranium metal is based on the possibility of reducing uranium chloride, obtained by chlorination reduction of uranium oxide as found in chloride alkali cells, to uranlum amalgam. If the reaction agents are well mixed, more than 90% of the reaction is completed after four hours at about 300 deg C, with only a slight excess of sodium amalgam. The batch thus obtained, a homogeneous mixture of araalgara, sodium chloride, and non-converted parts of uranium chloride, can be separated by short acid-treatment. After most of the mercury is filtered off from the uranium amalgam, the remaining mercury is distilled off in vacuum. By using a special smoldering technlque, products with less than 6 to 7 ppm Hg are obtained. The technique is advantageous not only because it reduces chemical costs by using cheap sodium amalgam instead of expensive pure calcium metal and chloride instead of hydrofluoric acid, but also because it raskes it possible to alloy the uranium directly with other metals in the amalgam phase, and to obtain sinterable powders instead of compact metals, the former being more suitable for the manufacture of uranium compounds and cermets with various structures.
