Thallium barium calcium copper oxide

Schematic layered structure of TBCCO-2223.

Thallium barium calcium copper oxide, or TBCCO (pronounced "tibco"), is a family of high-temperature superconductors having the generalized chemical formula Tl_mBa₂Ca_n−1Cu_nO_2n+m+2.

Tl₂Ba₂Ca₂Cu₃O₁₀ (TBCCO-2223) has a critical temperature (Tc) of 127 K, discovered in 1988.^[1]
