· Y4 Se4 O12 F4

Y₄Se₄O₁₂F₄ is a rare-earth oxyselenide fluoride ceramic compound containing yttrium, selenium, oxygen, and fluorine. This is a specialized research ceramic material, likely of interest for photonic, electronic, or structural applications where the combination of rare-earth elements and mixed anionic chemistry (oxide-fluoride hybrid) offers tailored properties such as optical transparency, thermal stability, or ionic conductivity not available in conventional oxide ceramics.
