摘要
本文研究了溶液循环流动法生长大截面ＫＤＰ晶体的工艺条件．发现影响晶体生长的关键因素是溶液的充分过热、流动体系的流量和生长相的温场．测定了不同条件下生长槽的温场，确定了最佳晶体生长区域。用循环流动法能提高溶液的过饱和度、加快晶体生长速度．
The growth of large KDP crystals is studied by solution circulating method.The key factors influemcing the crystal growth are the flow rate of the system,temperature distribution of the crystallizer and the temperature difference between superheater and saturator.The best growth zone is established through determining the temperature distribution of the crystallizer.The growth rate can be increased by increasing and accurate controlling of the supersaturation of the solution in this system.
