· JVASP-57803· PbSe2O6

PbSe₂O₆ is a mixed-valence lead selenite ceramic compound combining lead, selenium, and oxygen in a structured oxide framework. This material belongs to the family of heavy-metal selenite ceramics and is primarily encountered in materials research rather than widespread industrial production, with applications focused on optical, electronic, and specialized functional ceramic properties. Its potential relevance lies in photonic devices, radiation shielding, and advanced ceramic matrix composites where the high atomic mass and selenium chemistry offer advantages over conventional oxides.
