· JVASP-132881· BaY2Si2O7F2

BaY2Si2O7F2 is a barium yttrium fluorosilicate ceramic compound that combines rare-earth and alkaline-earth elements in a layered silicate structure. This material is primarily investigated in research contexts for optical and luminescent applications, particularly as a host matrix for rare-earth doping in phosphors and potentially in high-temperature ceramic coatings where fluorine-containing silicates offer improved thermal stability and lower melting points compared to conventional oxide ceramics. The fluorine component distinguishes it from standard silicate ceramics, enabling tailored photoluminescence properties valuable for display technologies, solid-state lighting, and scintillation detection systems.

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.
