Crystal preparation apparatus and crystal preparation method

Abstract

A crystal preparation apparatus (100) and a crystal preparation method (700). The crystal preparation apparatus (100) comprises: a growth cavity (110), the growth cavity (110) being internally provided with at least one layer of plate assembly (111); and a heating assembly (120), used for heating the growth cavity (110). The crystal preparation method (700) comprises: placing a raw material in the growth cavity (110) (710), the growth cavity (110) being internally provided with at least one layer of plate assembly (111); heating the growth cavity (110) by means of the heating assembly (120) so as to melt the raw material into a melt (720); bonding a seed crystal (180) to a seed crystal holder (150) (730); lowering the seed crystal holder (150) to which the seed crystal (180) is bonded, so that the seed crystal (180) is in contact with the melt; and preparing a crystal on the basis of the seed crystal (180) and the melt (750).
