Sb crystals through forced convection in the melt

Abstract

Abstract It was demonstrated that forced convection or mixing in the melt during directional solidification of bulk In V Ga \V Sb (0(x(0.1) ternary alloys significantly reduces cracks in the crystals. In this study, the enhanced mixing in the melt was generated by a rotating submerged baffle. The resultant improvement in spatial compositional homogeneity lowers the strain gradient or chemical stresses; thus eliminating cracks. The results presented are generally beneficial and should also improve the crystalline quality of other mixed alloys
