· ScTmO3

ScTmO3 is a rare-earth oxide ceramic compound combining scandium and thulium with oxygen in a perovskite or related crystal structure. This is primarily a research material studied for its potential in high-temperature applications, optical devices, and specialized electronic ceramics where rare-earth dopants offer tunable properties. While not yet established in mainstream industrial production, materials in this family are of interest for their thermal stability, refractive index characteristics, and potential use in solid-state lasers and luminescent applications where lanthanide and scandium combinations provide rare-earth photonic functionality.

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.
