· ErRhO3

ErRhO3 is a perovskite ceramic compound composed of erbium, rhodium, and oxygen, belonging to the rare-earth transition-metal oxide family. This material is primarily of research and development interest for high-temperature applications, particularly in thermoelectric devices, catalysis, and solid-state electronic systems where the coupling of rare-earth magnetism with rhodium's electronic properties offers potential advantages. While not yet widely established in mainstream engineering applications, materials in this ceramic family are investigated for their thermal stability, electrical conductivity modulation, and potential use in extreme-environment energy conversion systems.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
