· Na2 Sm4 Ir2 O12

Na2Sm4Ir2O12 is a complex mixed-metal oxide semiconductor containing sodium, samarium, and iridium in a structured lattice. This is a research-stage compound rather than a commercial material, belonging to the family of rare-earth iridates that exhibit interesting electronic and magnetic properties potentially useful in advanced functional ceramics. Interest in this material class stems from potential applications in catalysis, energy storage, and solid-state electronics where the combination of rare-earth and platinum-group metal oxides can enable novel chemical or electronic behavior.
