Abstract

Et siktemål med den foreliggende oppfinnelse er å tilveiebringe en fremgangsmåte for fremstilling av en vismutbasert oksid-superleder som er i stand til å oppnå en høy kritisk strømtetthet, og en superledende ledning som inneholder en vismutbasert oksidsuperleder fremstilt etter denne fremgangsmåte. Oppfinnelsen er rettet på en fremgangsmåte for fremstilling av en vismutbasert oksid-superleder inneholdende en 2223-fase med en 2223-sammensetning i en blanding Bi-Sr-Ca-Cu eller (Bi,Pb)-SrCa-Cu, omfattende et første trinn bestående i å fylle inn i en metallhylse et råmateriale inneholdende en 2212-fase med en 2212-sammensetning i en blanding Bi-Sr-Ca-Cu eller (Bi,Pb)-Sr-Ca-Cu med en kritisk temperatur på høyst 21,1 0C, et andre trinn bestående i å foreta plastisk bearbeidelse av metallhylsen fylt med råmaterialet, og et tredje trinn bestående i en varmebehandling av metallhylsen fylt med råmaterialet.
