· Te4 Pb4 O12

Te₄Pb₄O₁₂ is a mixed-metal oxide semiconductor compound containing tellurium and lead in a 1:1 ratio. This material belongs to the tellurate family and is primarily of research interest for its potential in optoelectronic and photonic applications due to its semiconductor band gap and mixed-valence structure. While not widely commercialized in mainstream engineering applications, tellurium-lead oxides are studied for infrared sensing, photovoltaic devices, and as precursors for advanced ceramic semiconductors.
