Abstract

Superledende keramiske artikler såsom slike som er repre-sentert ved den generelle formel YBaCU0_, hvor 0<x<0,6, og en fremgangsmåte for fremstilling av dem. Utgangsmaterialer for slike artikler innbefatter kilder til yttriumoksyd, kobber(II)-oksyd og bariummonoksyd. De blandede keramiske materialer oppvarmes til en temperatur som er høyere enn 30% av materialenes smeltetemperatur, men lavere enn smeltetemperaturene, og deretter legges et isostatisk trykk på 5,5 x IOMPa under konsolidering av det keramiske materialet til et legeme med en densitet på minst 85% av materialenes teoretiske densitet. Den keramiske artikkel kan ytterligere modifiseres ved gleding og avkjøling i nærvær av oksygen.
