摘要
在布里奇曼晶体生长系统中,在确定温场,主要参数的条件下通过不同的多坩埚形式,进行CaF_2晶体的生长研究。观察到坩埚与晶体材料的热传导率严重地影响着界面形状的形成,进而影响着晶体的散射。在理论分析和实验的基础上,找出适宜的坩埚形式和生长方案。
In the Bridgman-stockbarger system with definite temperture field and main growth foctors, we study the growth of CaF_2 cryst- al in multi-crucibles and find that the thermal conductivity of cruc- ibles and the crystal have serious influerce on not only the interfa- ce shape but also the crystal scattering. On the basis of theory and experiment, we find out the right crucible and growth device.
