A slip from high-temperature superconducting precursor material for green ceramic sheets is described. As ceramic starting material for the sheet-casting process, the slip contains a precursor powder which consists of the elements Bi, Sr, Ca, Cu and O, and which is prepared by modified co-precipitation. The powder has a mean grain size of < 5 mu m and has a specific surface area of > 25 m<2>/g. A process for preparing the slip, a process for producing a cast component and a process for producing a high-temperature superconducting component are also described. <IMAGE> |
