CRUCIBLE, PROCESS FOR MANUFACTURING THE CRUCIBLE, AND PROCESS FOR MANUFACTURING A CRYSTALLINE MATERIAL BY MEANS OF SUCH A CRUCIBLE

摘要

The invention relates to a crucible (1) for the formation of a crystalline material by solidification by growth on seed, comprising a base (2), at least one side wall (3) orthogonal to the base (2) of the crucible (1), and means for representing the position of at least one seed intended to be positioned at the base of the crucible, said seed comprising at least first and second faces orthogonal to the base of the crucible. The representation means comprise at least two markers (4) that extend over the inner face of the at least one side wall (3) along an axis orthogonal to the base of the crucible (1). The respective positions of at least two of the markers on at least one of the side walls (3) define, in the crystalline material, a first cutting plane tangent to the first face of said seed and a second cutting plane tangent to the second face of said seed.
