· Ca4Bi6O13

Ca4Bi6O13 is an inorganic ceramic semiconductor compound combining calcium and bismuth oxides, belonging to the family of mixed-metal oxides with potential photocatalytic and electronic applications. This material is primarily of research interest rather than established industrial production, investigated for optoelectronic devices, photocatalysis under visible light, and potential use in radiation detection or scintillation applications due to bismuth's high atomic number. Its appeal lies in exploring alternatives to more common semiconductors in niche applications where bismuth's electronic properties and the tailored band structure of calcium-bismuth mixed oxides offer advantages over conventional materials.
