· JVASP-12770· Li2ThN2

Li2ThN2 is an experimental ceramic compound combining lithium, thorium, and nitrogen—a member of the nitride ceramic family. This material remains primarily in the research phase and has not achieved widespread industrial adoption; it is of interest to materials scientists exploring advanced ceramic systems with potential applications in nuclear fuel matrices, high-temperature structural applications, or specialized electrochemical devices. The inclusion of thorium positions this compound within nuclear materials research, where thorium-based ceramics are investigated as alternatives to conventional nuclear fuels and as components in advanced reactor designs.
