· JVASP-25639· Na3ScSi2O7

Na3ScSi2O7 is a rare-earth silicate ceramic composed of sodium, scandium, and silicon oxides, belonging to the family of engineered silicate ceramics. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in advanced ceramic composites, thermal barrier systems, and specialized optical or refractory applications where scandium's unique properties can be leveraged. The combination of rare-earth elements makes it notable for high-temperature stability and potential thermal or chemical resistance, though it remains less common than conventional silicate ceramics in mainstream engineering practice.

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.
