BiSrCaCuO(2223) superconductor was fabricated by the thermal pyrolysis method. The superconducting precursor produced by the dehydration of the gel at $120^{circ}C$ for 12 h is not in the amorphous state as expected but in a crystalline state. In this paper, the establishment of fabrication condition was examined so as to improve the related properties to the practical use of BiSrCaCuO superconductor, and we reported the production of the BiSrCaCuO by the pyrolysis method.
