Abstract ： The Pb-doped Bi-based amorphous solid has been prepared by the anvil quenching method from the melt. After annealing, we obtained the dense superconductor with onset and zero resistance temperature at 120K and 107K, respectively. X-ray powder diffraction ( XRD ) and selected area electron diffract ion ( SAED ) analysis show that there is mainly high Tc phase (2223 phase) in the sample, and scanning electron microscopy ( SEM ) observation of the surface of the sample reveals that the needle-like grain abound in sample. Energy dispersive analysis of X-ray ( EDAX ) indicates that the average composition of grains is Bi2 Pb0.3 Sr1.3 Ca1.7 Cu2.3 Oδ
