- 論文の詳細を見る
The effects of various metallic dopants on the superconductivity of the Tl-Ba-Ca-Cu-O system have been investigated. Metals (Zn, Cd, Al, In, Pb and Bi) control the rate of solid-state reaction and the volatility of Tl components. Increases in the electrical conductivity at room temperature and the superconducting volume fraction were achieved as the result of metallic doping. It is considered that metals promote the intergranular coupling of the superconductive particle and annihilate the ceramic pores in the sintering process.
