Device and process for preparing aluminum nitride crystals by adopting spontaneous crystal seed method

The invention belongs to the field of crystal preparation, and in particular relates to a device for preparing aluminum nitride crystals and a corresponding process. The invention provides the device and the process for preparing aluminum nitride crystals by adopting a spontaneous crystal seed method. The device comprises an inductive heating coil, an insulating layer, a crucible device and a crucible lifting device. The crucible device consists of a crucible body, a crucible cover and a cover sheet. A hole which is 1-2mm in diameter is formed in the crucible cover, the cover sheet is located above the crucible cover and completely shields the hole, and the area of the cover sheet is between those of the hole and the crucible cover. The preparation process comprises the two steps of: (1) obtaining aluminum nitride single crystals through spontaneous crystallization at the hole to be used as the crystal seeds due to limit of anisotropic crystalline characteristic of aluminum nitride and geometric dimension of the hole at lower temperature; and (2) obtaining large-dimensional aluminum nitride crystals by weakening the anisotropic crystalline characteristic of aluminum nitride at high temperature and meanwhile slowly adjusting the position of the crucible by lifting through the lifting device.
