METHOD FOR PRODUCING FLUORIDE CRYSTAL |
摘要 |
<p>Provided is an apparatus capable of producing a fluoride crystal in a very short period of time, and a method suitable for producing a fluoride crystal using the apparatus. The apparatus comprises a chamber, a window material, and the like, and is modified such that it can evacuate air from the chamber to provide a high degree vacuum there. The apparatus further includes a crucible, which has a perforation at its bottom. The capillary portion of the perforation is adjusted to facilitate the contact of a seed crystal with a melt. By using the apparatus it is possible to stably produce high quality single crystals of fluorides in a short period of time.</p> |
