摘要：

Growth of paratellurite single crystals by the Czochralski method in an apparatus with resistance heating was investigated. It was found that forced convection in the melt was predominant besides the initial stage of the growth process. The dependence between the diameter of the crystal corresponding to the inversion of the flows in the melt and the rotation rate was investigated, and the importance of the vertical temperature gradient in the crucible was pointed out. It was compared with results obtained by other authors when RF heating was used.
