This article gives an overview on the processing techniques for Bi-based high temperature superconductors (HTS). As BiPbSrCaCuO is very complicated, multiphase system it is difficult to achieve a single phase with high critical transition temperature. The typical processing process for fabrication of HTS wire and tape is called powder-in-tube method. In this process, powder processing, mechanical deformation and thermal treatment have been well identified to be the most important steps for achieving the best performance. Various recent developments in these areas are carefully reviewed and alternative techniques are also presented, including continuous process and processes for making thick films.
