· Ca1 Rh1 O3

CaRhO₃ is a mixed-valence perovskite ceramic compound containing calcium, rhodium, and oxygen in a 1:1:3 stoichiometric ratio. This is a research-phase material studied primarily for its electronic and catalytic properties within the broader family of oxide perovskites, rather than an established commercial engineering material. Interest in this compound centers on potential applications in catalysis, electrochemistry, and solid-state electronics, where the rhodium d-electrons and perovskite crystal structure may enable novel ionic conductivity or redox activity; however, the scarcity and cost of rhodium metal limits practical deployment compared to more conventional perovskite alternatives.
