· JVASP-13148· Sr4Ti3O10

Sr₄Ti₃O₁₀ is a strontium titanate ceramic compound belonging to the Ruddlesden-Popper (RP) layered perovskite family, characterized by alternating layers of corner-sharing titanate octahedra and strontium cations. This material is primarily investigated in research contexts for applications requiring high-temperature stability, ionic conductivity, or photocatalytic activity, with particular interest in solid oxide fuel cells (SOFCs), oxygen ion conductors, and visible-light photocatalysis where layered perovskites offer tunable electronic and transport properties distinct from conventional simple perovskites.
