摘要

The device comprises a crucible (1), which is surrounded by a jacket heating element (6) and disposes on both sides over movable insulation elements (7), where the jacket heating element is upwardly movably arranged. The insulation elements are arranged to a side or downwardly arranged or movably arranged to a side or downwardly movably arranged. The device has a seed bag for receiving a crystal seed (2), where the seed bag is fixed at the bottom of the crucible. An independent claim is included for a method for growing crystals.
