Abstract

CE PROCEDE CONSISTE A FAIRE FONDRE DU SILICIUM BRUT, A MAINTENIR LE SILICIUM FONDU 10 AU-DESSUS DE SA TEMPERATURE DE SOLIDIFICATION DANS UNE ATMOSPHERE DE GAZ INERTE, ET A FAIRE TOURNER UN ELEMENT DE REFROIDISSEMENT ROTATIF CREUX 12 EN LE MAINTENANT IMMERGE DANS LE SILICIUM FONDU 10, TOUT EN INTRODUISANT UN FLUIDE DE REFROIDISSEMENT DANS L'ELEMENT 12 POUR FAIRE CRISTALLISER LE SILICIUM DE PURETE ELEVEE 15 SUR LA SURFACE EXTERIEURE DUDIT ELEMENT 12. L'APPAREILLAGE POUR LA MISE EN OEUVRE DE CE PROCEDE COMPREND: UN FOUR DE FUSION 1 EQUIPE D'UN DISPOSITIF DE CHAUFFAGE 5; UN CREUSET 2 DISPOSE A L'INTERIEUR DU FOUR DE FUSION 1; UN MOYEN 4, 8 POUR MAINTENIR DANS UNE ATMOSPHERE DE GAZ INERTE LE SILICIUM FONDU 10 PLACE DANS LE CREUSET 2; UN ELEMENT DE REFROIDISSEMENT ROTATIF CREUX 12, DISPOSE DANS LE CREUSET 2; ET UN MOYEN 13 POUR INTRODUIRE UN FLUIDE DE REFROIDISSEMENT A L'INTERIEUR DE L'ELEMENT DE REFROIDISSEMENT 12.
