Methods of preparing Zn-Th alloy electrolytically followed by the vacuum distillation of alloy to get a pure Th have been studied. In electrolysis, graphite crucible with a capacity of 300g salt have been used as the anode and fused Zn as the cathode. Temperatures around 800°C have been found. preferable to 700°C in order to get a high content of Th in Zn cathode and it has been shown that the highest content of Th in the alloy without lowering the fluidity of the alloy is 15-20wt.%. The pure Th metal sponge can be produced by vacuum distillation of the alloy at 1000°C. It has been shown that this process is promising as a method of preparing pure Th metal sponge.
