| 摘要 |
According to this invention a process for forming a crystal of a substance comprises securing surfaces of two crystals (1) together with the axes of the crystals aligned and depositing said substance onto the joined crystals thereby causing them to grow into a single crystal substantially or entirely surrounding the registering regions (2) of said surfaces. A resultant crystal may be sectioned to provide large, single crystals (3) not containing a bonded region. |
