Abstract (en)
[origin: WO2022061384A1] The invention relates to a device for growing single crystals, in particular single crystals of silicon carbide, comprising a crucible (601), which crucible (601) defines an outer lateral surface and furthermore delimits a receiving chamber (604) having an axial extension between a bottom section and an opening section, the receiving chamber (604) being designed to grow the crystals, the device comprising at least one seed crystal layer (602), wherein the crucible (601) is arranged in a chamber, in particular a chamber made of a glass material, for example quartz glass, wherein an induction heating is arranged around the chamber. The invention is characterized in that the crucible (601) has a multi-part design and comprises a crucible bottom part (302, 605), at least one crucible wall part (608) and a crucible cover part (303, 606), which are connected to one another in a detachable manner.
