Thallium barium calcium copper oxide

Thallium barium calcium copper oxide

Thallium barium calcium copper oxide, or TBCCO (pronounced "tibco"), is a family of high-temperature superconductors having the generalized chemical formula TlmBa2Ca"n"−1Cu"n"O2"n"+m+2+δ.

Tl2Ba2Ca2Cu3O10 (TBCCO-2223) has a Temperature coefficient (Tc) of 127 K, discovered in 1988.
