本文对不同坩埚热物性组合时计算得到的结果进行了比较.对各向同性坩埚而言,应该优先选择具有与晶体和熔体的导热系数相当导热系数的材料,也可选择导热系数较大的材料.在强度允许的情况下,减小坩埚壁厚对晶体生长有利.
本文對不同坩堝熱物性組閤時計算得到的結果進行瞭比較.對各嚮同性坩堝而言,應該優先選擇具有與晶體和鎔體的導熱繫數相噹導熱繫數的材料,也可選擇導熱繫數較大的材料.在彊度允許的情況下,減小坩堝壁厚對晶體生長有利.

The combinations of crucibles with different thermal properties were investigated. If the isotropic material is used for making crucible, the material having comparative thermal conductivity to the crystal and its melt or having larger thermal conductivity should be preferable.The material with small thermal conductivity is unfavorable. If the material is strong enough, thinner wall crucible will be good for crystal growth.
