【 摘 要 】

The silver sheath material plays an important role in the preparation of Bi-2212 and Bi-2223 tape conductors. In this paper, a chemical solution deposition method was proposed to fabricate the Bi-2212 thin film on Ag substrates after polishing and annealing. The influences of the sintering temperature were investigated. After sintered at 780°C or 790°C for 5 h in 8% O2(N2balanced), samples with almost pure and highly c-axis textured Bi-2212 phase were prepared. And the full width at the half maximum (FWHM) value of the rocking curves for the Bi-2212 (0012) plane reached below 5.8°.
