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.Crucible for the directed solidification of an ingot made of an ingot material chosen from silicon, germanium and their mixtures, comprising: - a mold comprising a bottom wall of the mold and a side wall of the mold extending from the wall of mold bottom along an axial direction, the mold bottom wall and the mold side wall together defining a cavity for containing the molten ingot material, and - a thermally insulating and hollow holding structure extending along the axial direction and comprising a structural side wall having a radial surface thermal resistance greater than the radial surface thermal resistance Rthpm of the mold side wall, the support structure encircling the mold side wall around the axial direction.
