· JVASP-101426· ScO2

Scandium oxide (Sc₂O₃) is a rare-earth ceramic compound that combines high structural rigidity with thermal stability, making it valuable in specialized high-performance applications. It is primarily used in advanced optics, refractory systems, and solid-state laser technology, where its optical transparency and resistance to thermal shock are critical advantages over conventional ceramics. The material appeals to engineers working in extreme-temperature environments or precision optical systems where conventional oxides would degrade or scatter light.

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.
