WebMar 15, 2024 · Thorium, as a nuclear-power replacement for the uranium-based nuclear reactors and an effective avenue to produce uranium source, has become a key element for the increasing energy demand. However, we now are seriously restricted to gain thorium from mineral, due to co-existence of thorium, uranium, and rare earth elements. Webmolten thorium fluoride in alkali fluoride mixtures have been systematically carried out to elucidate the variation of local structure of thorium cation in various melts. Experimental …
