The (Bi,Pb)-Sr-Ca-Cu-O glass-ceramics may be considered as disordered metal and superconductor. Depending on the heat treatment conditions the materials are either composed of the oval grains of the 2212 or 2201 phases embedded in the insulating matrix or they mainly contain the 2212 plate-like crys

Bi-pb-Sr-Ca-Cu-O bulk samples with nominal composition of Bil.6Pb0.4Sr2Ca3Cu4Oy (2234) were prepared by a melt casung method. The melting process was carried out on two different powders; one consisting of the precursor materials, and one in which the precursor had been calci,r,d.Th~-~ffects of the
An alternative synthetic route for obtaining (Bi, Pb)zCazSr,CujO, (2223), by using Bi2CaSr2Cuz0,, (2122), as a starting material is described. The advantages of this route include lower processing temperatures, shorter reaction times, and improved phase purity over conventional synthetic routes.
A series of solid solutions containing CO3 groups, (CyCul\_y)(Srl \_z/2Caz/2)2(Y1 \_xCax\_zSrz)Cu20 d with 0.30<x <0.70, was prepared at 1313 K under the atmosphere of 02-4202. The values ofy (0.48-0.67) and z (0.14--0.28) depend on the total Ca content, x. The length of the a-axis increases from 3.
