· ErSmO3

ErSmO3 is a rare-earth oxide ceramic compound combining erbium and samarium in a perovskite or related crystal structure. This is primarily a research material rather than an established commercial product, studied for its potential in high-temperature applications, solid-state electronics, and specialized optical or magnetic devices that exploit rare-earth element properties. The material belongs to the family of rare-earth oxides, which are investigated for advanced ceramics, catalysis, thermal barrier coatings, and emerging semiconductor applications where the combination of erbium and samarium offers tunable electronic or phononic behavior.

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.
