摘要

We have fabricated a series of glass-ceramic (Bi{sub}(2-δ)Zn{sub}δ)Sr{sub}2Ca{sub}2Cu{sub}3O{sub}(10+y), where δ = 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0, and investigated the effect of Zn ions on the glass formation, crystallization, thermal, electrical, and on the magnetic properties of the BSCCO-2223 superconductor system. The structural symmetry was found to be tetragonal in all the substitution levels. The best electrical performance was obtained from the δ = 0 sample, the T{sub}c and T{sub}(zero) was obtained at 110 K and 107 K, respectively. The J{sub}c values of the samples were determined using the magnetization hysteresis and Bean's model. The crystallization kinetics were investigated using nonisothermal models of Augis-Bennett. The calculated activation energy, E{sub}a, of the system was found to be in the range of kJ/mol.
