Abstract

En stivnet masse for et multikrystallsilisiummateriale av høy renhet som fortrinnsvis anvendes for fremstilling av krystalltypesilisiumingoter for fotogalvaniske elementer, og en fremgangsmåte for fremstilling av den stivnede massen er tilveiebrakt. Silisiummassen stivnet fra smeltet tilstand ifølge oppfinnelsen er en stivnet masse fremstilt ved å dryppe smeltet silisium i et mottakskar og tillate karet å motta det smeltede silisiumet, den stivnede massen inneholder bobler og har (i) en tilsynelatende tetthet på ikke mindre enn 1,5 g/cm3 og ikke mer enn 2,2 g/cm3 og (ii) en trykkfasthet på ikke mindre enn 5 MPa og ikke mer enn 50 MPa. Fremgangsmåten for fremstilling av en silisiummasse stivnet fra smeltet tilstand ifølge oppfinnelsen er en fremgangsmåte omfattende å dryppe smeltet silisium i et mottakskar og tillate karet å motta det smeltede silisiumet, hvori karets overflatetemperatur for å motta det smeltede silisiumet ikke er lavere enn 0 (C og ikke høyere enn 1 000 (C, og mottakskaret tillates å motta det smeltede silisiumet i en hastighet på 1 x 10-3 til 5 x 10-1 g/s·cm2.
