This paper describes the experimental study of the conditions for heat and mass transfer in horizontal directional crystallization of refractory oxide compounds in the case of heating the rear part of the container from below. It is established that such heating causes significant changes in the nature of mass transfer in the central region of the liquid layer. As a result, a stable structure is formed, ensuring the supply of liquid from the rear part of the container to the crystallization front, mass transfer in the near-surface and near-bottom vortices, and more efficient mixing of the melt.
