· Sr4 Er2 Ru2 O12

Sr₄Er₂Ru₂O₁₂ is a complex mixed-metal oxide ceramic compound containing strontium, erbium, and ruthenium in a highly ordered crystalline structure. This is a research-phase material primarily investigated for its electronic and thermal properties in advanced functional ceramics, rather than a commercial commodity. The compound is of interest in materials science for potential applications in high-temperature electronics, oxide ion conductors, and exotic semiconductor devices where the combination of rare-earth (Er), alkaline-earth (Sr), and transition-metal (Ru) chemistry creates unique electronic states.
