· JVASP-9800· ZnBi2O5

ZnBi₂O₅ is a mixed-metal oxide ceramic compound combining zinc and bismuth oxides, belonging to the family of heavy-metal oxide ceramics. This material is primarily investigated in research contexts for applications requiring high-density ceramics with potential photocatalytic or electronic properties, particularly in bismuth oxide-based systems known for their visible-light activity and applications in photocatalysis and optoelectronics. Engineers and researchers select zinc bismuth oxide compounds over simpler single-oxide alternatives when simultaneous benefits of zinc's chemical stability and bismuth's photocatalytic responsiveness are needed, though the material remains largely in development rather than widespread industrial production.
