Abstract

SAMMENDRAG Fremgangsmåte for rensing av lavrent metallurgisk silisium som inneholder minst én kontaminant, for oppnåelse av et renere, fast og polykrystallinsk silisium. · Fremgangsmåten innbefatter anordning av en smelte av lavrent metallurgisk silisium i en form som har en isolert bunn og isolerte sidevegger og en åpen topp. Smelten størkner med ensrettet størkning fra den åpne toppen og mot bunnen, samtidig som smelten omrøres elektromagnetisk. Raten for den ensrettede størkningen styres. Den ensrettede størkningen stoppes når smelten er delvis størknet, for derved å tilveiebringe en barre som har et ytre skall som innbefatter det renere, faste og polykrystallinske silisiumet og har et senter med urenhetsanriket flytende silisium. I barrens ytre skall tilveiebringes det en åpning slik at det urenhetsanrikede flytende silisiumet kan strømme ut, hvorved det blir igjen et ytre skall med det renere, faste og polykrystallinske silisiumet.
