X-ray diffraction and electrical and diamagnetic analyses revealed that the 2223 phase was significantly enhanced by highvalence cation \(\left(\mathrm{V}^{5+}, \mathrm{Nb}^{5+}, \mathrm{Ta}^{5+}\right.\), etc.) doping in \(\mathrm{BiSrCaCuO}\) samples. The optimum nominal composition was \(\mathrm{
Annealing effects of two step heat treatment have been studied on BiSrCaCuO films made by screen printing. The volume fraction of high T c phase is sensitive to the temperature of first step. The method has proved effective in obtaining large volume fraction of high T c phase.
