摘要
The present invention relates to a process for the production of a high-Tc superconductor as precursor material for the oxide-powder-in-tube method, in which the oxides of the elements Bi, Sr, Ca and Cu are mixed and completely melted at temperatures of /= 1000@C, in which the melt is cast onto a substrate which is maintained at room temperature and in which the cooled melt block is comminuted and ground to a powder.
