ceramic· JVASP-143646· K5Pr4Si4O16F
K5Pr4Si4O16F is a rare-earth silicate fluoride ceramic compound containing potassium, praseodymium, silicon, oxygen, and fluorine. This is a research-phase material primarily studied for its potential in photonic and luminescent applications, where the praseodymium rare-earth dopant enables fluorescence or photoluminescence under specific excitation. While not yet widely adopted in mainstream manufacturing, materials in this silicate-fluoride family are investigated for optical devices, scintillators, and potentially laser-active ceramics where the combination of rare-earth functionality and fluoride-enhanced properties offers advantages over conventional oxide ceramics.

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.
