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.对各向异性坩埚而言,纵向导热系数应该优先选择较小的材料;也可选择具有与晶体和熔体的导热系数相当导热系数的材料.横向导热系数则越大越有利于晶体生长.复合坩埚两种坩埚材料的导热系数最好不要相差太大.

The combinations of crucibles with different thermal properties were investigated. If the anisotropic material is used for making single layer crucible, it is preferable for the material larger thermal conductivity along transverse direction, small thermal conductivity along longitudinal direction or having comparative thermal conductivity along longitudinal direction to the crystal and its melt. It is unfavorable for material with small thermal conductivity along transverse direction and large thermal conductivity along longitudinal direction. For composite crucible, the conductivity of the two materials should be very close.
