Abstract
Two sol-gel (citrates and acetates- derived) methods for the 2223 BiSCCO precursor powders and film preparation were studied. The acceleration of diffusion processes due to intimate cation mixing and homogeneity on atomic scale provides the effective shortening of the sintering time for the 2223-phase formation. In the case of fluorinedoped Bi(Pb)SCCO, single phase 2223 sample is formed after 48 h sintering at 840°C. The multi-core composite Ag/BiSCCO highly c-axis textured tapes and multifllament wires were fabricated by slurry casting and powder-in-tube methods, respectively.
