Sr2 Sm1 Ta1 Cu2 O8

Sr2Sm1Ta1Cu2O8 is a complex mixed-metal oxide ceramic combining strontium, samarium, tantalum, and copper in a layered perovskite-related structure. This is a research-phase compound of interest primarily in functional ceramics, particularly for its potential electrochemical and electronic properties arising from the rare-earth (samarium) and transition-metal (copper, tantalum) dopants. While not yet widely deployed in commercial applications, materials in this family are investigated for solid-state ion conductors, catalytic substrates, and high-temperature electronic devices where the interplay of rare-earth and d-block metal cations can produce tunable conductivity and redox activity.
