· Ba2 Y1 Ti2 Tl1 O7

Ba₂Y₁Ti₂Tl₁O₇ is a complex mixed-metal oxide ceramic compound containing barium, yttrium, titanium, and thallium—a composition that places it in the family of perovskite-related structures with semiconductor behavior. This material is primarily of research and experimental interest rather than established commercial production, representing an investigation into how rare-earth and heavy-metal dopants modify the electronic and structural properties of titanate ceramics. The thallium incorporation and multi-cation coordination make this compound relevant to exploratory work in functional ceramics, where researchers are evaluating novel oxide compositions for potential applications in electroceramics, optical properties, or advanced dielectric systems.
