Ba4 Y2 F14
ceramic· Ba4 Y2 F14
Ba₄Y₂F₁₄ is a barium yttrium fluoride ceramic compound belonging to the rare-earth fluoride family, which exhibits optical and thermal properties valuable in specialized applications. This material is primarily investigated for solid-state laser host matrices and thermal barrier coatings, where its fluoride structure provides excellent transparency in the infrared spectrum and chemical stability at elevated temperatures. Compared to oxide-based ceramics, fluoride compounds like Ba₄Y₂F₁₄ typically offer lower phonon energies and reduced quenching effects, making them attractive for photonic applications, though they remain largely in research and development rather than high-volume commercial production.

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.
