Sr2Ti2Bi2OF2

Sr2Ti2Bi2OF2 is a mixed-metal oxide ceramic compound containing strontium, titanium, and bismuth with fluoride anions, representing an experimental phase in the family of complex perovskite-related oxyfluorides. This material is primarily of research interest rather than established industrial use, with potential applications in electronic ceramics, photocatalysis, or solid-state ionics where the combination of d-block and post-transition metal cations can produce novel functional properties. The inclusion of both oxide and fluoride ligands distinguishes it from conventional titanates and may enable tuning of electronic structure, dielectric response, or photochemical activity in ways not easily achieved with single-anion systems.
