Abstract We present the results of the experimental study on heat and mass transfer in horizontal directional crystallization of high-melting oxide compounds. We considered the case of heating of the rear part of the growth container by means of the heater radiation through the slot in the platform of the container. It is established that such heating causes significant changes of mass transfer in the central part of the liquid layer. As a result, a stable structure is formed that ensures the flow of liquid from the back of the container to the crystallization front. A more effective mixing of the melt and a more advantageous shape of the crystallization front is achieved. The results of the model experiments were checked and proved by the growth process of chrysoberyl crystals doped by the chromium oxide.

水平定向结晶过程中热边界条件对传热传质的影响

摘要 我们介绍了高熔点氧化物水平定向结晶传热传质实验研究的结果。我们考虑了通过容器平台中的槽口的加热器辐射加热生长容器后部的情况。已确定这种加热会导致液体层中心部分的传质发生显着变化。结果，形成了稳定的结构，确保液体从容器后部流向结晶前部。实现更有效的熔体混合和更有利的结晶前沿形状。通过氧化铬掺杂的金绿玉晶体的生长过程验证了模型实验的结果。
