· JVASP-9863· Ca2YBiO5

Ca₂YBiO₅ is a mixed-metal oxide ceramic compound containing calcium, yttrium, and bismuth. This material belongs to the family of rare-earth-containing oxides and is primarily of research interest for applications requiring high-density ceramics with potential photocatalytic or radiation-shielding properties. While not yet widely deployed in mainstream industrial applications, materials in this chemical family are being investigated for specialized functions including scintillators, photocatalytic water treatment, and radiation absorption in nuclear or medical imaging contexts.
