The Impact of Melt Transparency on Li2MoO4 Single Crystal Growth by the Czochralski Technique

Year: 2024

Type: article

Abstract: In this paper, it is found that taking a semitransparent melt, influences c–m interface shape, heat transfer, melt flow and von Mises thermal stress distributions, therefore the quality of the grown crystal. As a result, when absorption coefficients of both melt and crystal change from transparent to opaque case, the c–m interface convexity reduces from 12.5 to 5.8 mm, its shape becomes more convex toward the melt, and the maximum von Mises thermal stresses decreases from 69.55 to 13.8 MPa. For the second study, where the crystal absorption coefficient is fixed at , the c–m interface convexity increases with the increase in melt absorption coefficient. The maximum and minimum von Mises stresses for the case are low compared to other values; then the grown crystal has a good quality.
