K3ScSi2O7
ceramic· JVASP-25667· K3ScSi2O7
K3ScSi2O7 is a rare-earth silicate ceramic compound containing potassium, scandium, and silicon oxide phases. This material belongs to the family of advanced silicate ceramics and appears to be primarily a research compound rather than an established commercial material; it is investigated for high-temperature structural applications where scandium incorporation offers improved thermal and mechanical stability compared to conventional silicates. The potassium-scandium-silicate system represents an emerging material class of interest for specialized refractory, optical, or electronic ceramic applications where rare-earth doping enhances performance.

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.
