<P>PROBLEM TO BE SOLVED: To provide a crystal production method in which a crack in a crucible is prevented and a crystal is produced with less unintended impurities mixed therein. <P>SOLUTION: The crystal production method includes: a process of preparing a crystal production apparatus in which a buffer layer 110 is arranged between the crucible 101 inner wall 101a and raw materials 17; and a process of growing the crystal in the crystal production apparatus. In the preparation process, the buffer layer 110 is arranged which has a melting point higher than a temperature to grow the crystal in the growing process and also has at least either of higher ductility and higher brittleness than the materials that composes the crucible 101. <P>COPYRIGHT: (C)2013,JPO&INPIT |
