Abstract

En gjenstand for oppfinnelsen er å tilveiebringe en fremgangsmåte for fremstilling av en stor mengde rimelig silisium med høy renhet som kan benyttes i solarbatterier eller solceller. Det beskrives en firemgangsmåte fior firemstilling av høyren silisium ved migrering av urenheter i smeltet sihsium til slagg og som inkluderer tilmåting av et oksidasjonsmiddel til det smeltede silisium sammen med slagg og der oksidasjonsmidlet er et materiale som omfiatter som primærkomponent minst et av fiølgende materialer: alkalimetall karbonat, hydrat av alkalimetall karbonat, alkalimetall hydroksid, jordalkalimetall karbonat, hydrat av jordalkalimetall karbonat eller jordalkalimetall hydroksid.
