Abstract

Creuset pour la solidification dirigée d'un lingot en un matériau de lingot choisi parmi le silicium, le germanium et leurs mélanges, comportant : - un moule comportant une paroi de fond de moule et une paroi latérale de moule s'étendant depuis la paroi de fond de moule le long d'une direction axiale, la paroi de fond de moule et la paroi latérale de moule définissant ensemble une cavité pour contenir le matériau de lingot en fusion, et - une structure de maintien thermiquement isolante et creuse s'étendant selon la direction axiale et comportant une paroi latérale de structure présentant une résistance thermique surfacique radiale supérieure à la résistance thermique surfacique radiale Rthpm de la paroi latérale de moule, la structure de maintien ceinturant la paroi latérale de moule autour de la direction axiale.
