· ErHoO3

ErHoO3 is a rare-earth oxide ceramic compound combining erbium and holmium oxides, belonging to the broader family of lanthanide-based functional ceramics. This material is primarily investigated in research contexts for applications requiring high refractive index, optical transparency, or thermal stability at elevated temperatures. ErHoO3 and related rare-earth oxides are of interest in photonics, thermal barrier coatings, and specialized optical components where the combined properties of multiple lanthanides offer advantages over single rare-earth alternatives.

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.
