Explanation
Thallium is the abbreviation of the high-temperature superconductor family. The superconductor critical temperature Tr is 20K, 108K and 125K respectively. The density of superconductor is 1021 electrons per cubic centimeter. The carrier type is hole type, namely P type; Debey temperature 0 is 238-290K; the crystal structure is oxygen deficient perovskite. T phase. Due to the strong toxicity of T1, the preparation of this materials is difficult. It has no practical value in strong electricity; It has certain applications in superconducting electronics.
