摘　　要：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。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.
