Thorium carbide, reaction with iodine

Thorium and Pa are most conveniently prepared from carbides, but at low temperatures made possible by an iodide intermediate in the iodine vapor process, based on the reaction of carbide with iodine vapor at 300 C. The actinoid iodide is transported to a hot surface (such as a W wire or sphere at 1200°C), where it decomposes and deposits the actinoid metaF". The overall reaction sequence is...
