Modeling the Distribution of Temperature Fields at the Initial Stages of Growth of a Monocrystal of Sapphire
Calculations of heat transfer in the crystallization zone, taking into account the convection of the melt for various growth conditions (rotational speed, crystal pulling speed, the height of the crystal) were made. The dependence of the cone sprouting crystal depth in the melt on its height and rotation speed and time of the crystal growth mechanism change at the initial stage of seeding were determined.
