This paper reports the crystallization and superconducting properties of Bi{sub 4}Sr{sub 3}Ca{sub 3}Cu{sub 4}O{sub x} glass-ceramics. The glass was prepared using the conventional melt-quenching method. X-ray diffraction pattern has shown that the annealing at temperature of 800 C converted the glass into glass-ceramics with Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub x} superconducting phase (2212-phase). The superconducting transition exhibits the change in the slope that is characteristic for two different superconducting phases. It is observed that {Tc} (zero) increases from 20 K to 80 K with increasing time of annealing. The influence of magnetic field on the superconducting transition has been investigated. The studies revealed a remarkable broadening of the resistive transition as a function of temperature with increasing field. The temperature width ({Tc}-T) of the transition for both phases increases with magnetic field according to Tinkham model.
