Abstract (en)
[origin: CA2845068A1] The crystallization system comprises a crucible (1) provided with a base (2) and side walls (3) that is intended to contain the material to be solidified and a device (4) for creating a main thermal gradient inside the crucible (1) in a direction perpendicular to the base (2) of the crucible (1). An additional induction heating device (6) is positioned at the side walls (3) of the crucible (1) facing the liquid material and without overlapping with the solid phase. This additional induction heating device (6) is configured in order to heat a portion of the crystalline material located in the vicinity of the triple line between the liquid material, the solidified material and the crucible (1) so that the interface (10) between the liquid material and the solidified material forms a convex meniscus in the vicinity of the triple line.
