THORIUM FUSED SALT ELECTRODEPOSITION INTO A MOLTEN ZINC CATHODE

Technical Report ·
OSTI ID:4800476
An improved technique has been developed for electrorefining thorium into molten zinc at 600 deg C, using a fused salt bath of LiCl-KCl-ThCl/sub 4/. Stirring the zinc markedly improved the current efficiency. Fifteen weight percent ThCl/sub 4/ was found to be the concentration at which approximately l00% current efficiency is obtained at the cathode between current densities of 0.02 and 0.53 amp/cm/sup 2/. The practical limit for the deposition of thorium into zinc at 600 deg C is about 15 wt%, at which concentration the alloy becomes paste- like and renders stirring difficult. (auth)
