ReMgO3

ReMgO₃ is a rare-earth magnesium oxide perovskite ceramic compound combining rhenium (or rare-earth elements denoted 'Re') with magnesium and oxygen in a 1:1:3 stoichiometry. This material belongs to the family of complex oxide ceramics and is primarily of research and developmental interest rather than established in high-volume industrial production. The perovskite structure makes it a candidate for specialized applications in high-temperature ceramics, solid-state ionic conductors, and advanced functional materials where rare-earth doping and mixed-metal oxides offer unique electronic, thermal, or crystallographic properties.
