· Mg4 V4 Bi4 O20

Mg₄V₄Bi₄O₂₀ is a complex mixed-metal oxide semiconductor compound combining magnesium, vanadium, and bismuth in a layered or framework structure. This is primarily a research material under investigation for semiconductor and photocatalytic applications rather than an established engineering material in widespread commercial use. The vanadium-bismuth oxide system is of interest for potential applications in catalysis, photochemistry, and solid-state electronics due to the electronic properties imparted by vanadium's multiple oxidation states and bismuth's polarizable structure.
