摘要：
We have investigated the effect of Pt on crystallization of Bi2Sr2Ca1Cu2Oy prepared by the melt process. By observing the microstructure of specimens rapidly cooled in the process of crystallization, we found that the Pt restrained the growth of the Ca2Cu1O3 Phase and even or superconducting phases. It was found that Pt formed oxides preferentially with Ca and Sr early in the crystallization process, however, such products didn't seem to grow coarsely.
