· Mg4 Ta2 Nb4 O16

Mg₄Ta₂Nb₄O₁₆ is a mixed-metal oxide ceramic compound combining magnesium with refractory transition metals (tantalum and niobium), belonging to the family of complex oxide semiconductors. This is primarily a research material explored for its potential in high-temperature electronics, photocatalysis, and advanced ceramic applications where the combination of magnesium's light weight with tantalum and niobium's chemical stability and electronic properties offers tailored functionality. The material's appeal lies in its ability to operate in extreme thermal environments and its tunable bandgap characteristics, making it a candidate for next-generation semiconducting ceramics where conventional oxides fall short.
