Fremgangsmåde til fremstilling af keramiske superlederfilamenter

摘要

A method of making ceramic superconducting wires comprising - a step of performing at least one process including mixing starting materials (such as oxides of the constituent metals or compounds containing the metals an oxidised state), shaping the mixed ceramic superconductor so obtained into a ceramic superconductor body of a predetermined shape, sintering it and subsequently grinding the sintered ceramic superconductor body; - a step of transferring the resulting ceramic superconductor powder (1) to a glass tube (2); - a step of heating the whole glass tube or a local portion of it in a heating and melting device (4) so as to melt the ceramic superconductor powder (1); - a step of spinning the glass tube so as to obtain a ceramic superconducting wire (8). A multiple conductor cable (12) can further be formed when a plurality of said ceramic superconducting wires (8) are bundled and put in a glass tube and subsequently heated and spun. Metal wires can further be bundled with said ceramic superconducting wires (8).
