Abstract: The invention is related to a package for packing a cylindrical carbon heater, used for manufacturing a mono crystal body and a method of forming the same, in which the cylindrical carbon heater is held sandwiched at the opposite ends between a base member and a plurality of retainer members, and compressive forces are applied independently to different parts of the carbon heater on the base member via the respective retainer members.

Abstract: A method of manufacturing split crucible pieces of a multiple-piece crucible comprising an integral assembly of two or more split crucible pieces and having a spherical bottom inner surface. The split crucible pieces are manufactured from a work mass graphite material by mechanical processing, comprising a step of forming a blind annular groove coaxial with the work by cutting the work from an end thereof toward the other end, a step of axially splitting the work into two or more pieces, constituting eventual split crucible pieces, and a step of cutting each split crucible piece from the side thereof opposite the sector-like or polygonal profile surface side by using a spherical acutting means, thereby forming a spherical inner bottom surface.
