· JVASP-29463· Si3Bi2O9

Si₃Bi₂O₉ is a bismuth silicate ceramic compound belonging to the family of mixed-metal oxide ceramics. This material is primarily of research interest rather than widely commercialized, with potential applications in specialized oxide ceramics where bismuth's properties—including high density, thermal stability, and possible electronic functionality—could be leveraged alongside silicate structure. The bismuth silicate family is explored for emerging applications in photocatalysis, solid electrolytes, and high-temperature structural ceramics where conventional silicates may fall short.
