Abstract
Bulk samples containing nearly single phase of the three Cu-O layered compound in the Tl-Pb(Bi)-Sr-Ca-Cu-O system have been readily synthesized. By partially substituting Ca for Sr, an accelerated formation of the desired three Cu-O layered phase was observed when the Ca/Sr ratio reached up to 2.4/1.6. The phase purity was clearly evidenced by x-ray diffraction and magnetization measurement. The synthesis is valuable for further application interests.Keywords
