Melting and vaporization of the 1223 phase in the system (Tl-Pb-Ba-Sr-Ca-Cu-O)

Abstract: The melting and vaporization of the 1223 [(Tl,Pb):(Ba,Sr):Ca:Cu] oxide phase in the system (Tl-Pb-Ba-Sr-Ca-Cu-O) have been investigated using a combination of dynamic methods (differential thermal analysis, thermogravimetry, effusion) and post-quenching characterization techniques (powder x-ray diffraction, scanning electron microscopy, energy dispersive x-ray spectrometry). Vaporization rates, thermal events, and melt compositions were followed as a function of thallia loss from a 1223 stoichiometry. Melting … Show more

“…The melting and vaporization of the 1223 phase have been investigated using a combination of dynamic methods (differential thermal analysis, thermogravimetry, and effusion) and post-quenching characterization techniques (scanning electron microscopy, energy dispersive x-ray spectrometry, and powder x-ray diffaction) [126]. The melting and vaporization equilibria of the 1223 phase are complex, with as many as seven phases participating simultaneously.…”

“…Among the Tl 1 Ba 2 Ca n-1 Cu n O 2n+2 superconductors family the n=3 member is important due to its higher critical temperature, excellent fluxpinning properties, higher critical current and irreversibility field H irr [65][66][67][68][69][70]. The Tl-1223 was the first superconducting composition reported among the other members of this family [71]. The single-phase samples of Tl-1223 are difficult to prepare.…”
