Abstract Superconducting materials exhibit great potential in the fields of electricity, magnetic fields, and supercomputers due to their superior electrical conductivity, complete diamagnetism and Josephson effect. Bi-based high-temperature superconducting materials can achieve a critical use temperature higher than the liquid nitrogen boiling point of 77 K, can be made into strips and wires, and can carry a large current, is considered to be a very promising practical superconducting material. This paper mainly introduces the structure and main preparation process of Bi-based high-temperature superconducting materials. From the three main processes of preparing precursor powders, the related researches carried out in China are introduced, and the advantages and disadvantages of these preparation processes are briefly analyzed.
