本文的计算方法是根据对晶体生长炉中温场和热交换状态的实验研究提出的。用这种计算已成功地生长出大尺寸的CaF2和BaF2晶体(直径400mm),计算方法的准确性已为实验所证实,在许多新建或现有的生长系统中,结果都证明这种计算方法对于解决一些生长和退火问题是有效的。这种方法被广泛地用于估计各种复杂结晶容器的边界条件和在大晶体生长各个阶段的连续温场处理模型。这一点非常重要,因为迄今除了计算以外还没有其它方法可用于分析碱卤化合物材料的熔体—晶体系统的热状态,在用Stockbarger技术中,这些实验结果被成功地用于发展生长设备。
The calculation method of this paper is based on the experimental study of the temperature field and heat exchange in the crystal growth furnace. With this calculation, large crystals of CaF2 and BaF2 (diameter 400 mm) have been successfully grown. The accuracy of the calculation method has been experimentally confirmed. In many new or existing growth systems, the results prove that this calculation The method is effective to solve some growth and annealing problems. This method is widely used to estimate the boundary conditions of various complex crystallization vessels and the continuous temperature field treatment model in various stages of large crystal growth. This is important because so far there are no other ways to analyze the thermal state of the melt-crystal system of alkali halide compounds so far, and these results have been successfully used to develop growth equipment with Stockbarger technology.
