Liquid/solid interface profile of melt grown oxide crystals I. Czochralski growth

Abstract

The relation between temperature gradient and the liquid/solid interface profile of Czochralski grown Al2O3 and YAG crystals is described. Lowering the radial component as well as increasing the axial component of temperature gradient during crystal growth causes the convex or pointed interface to be flattened. In the range of magnitudes both of the components of temperature gradient used, four types of interface profiles were found. An alteration of the interface profile which causes local increase of the growth rate can be accompanied by cell formation. The volume of the portion of the growing crystal submerged in the melt is directly proportional to the optical transmissivity of the crystal and inversely proportional to the optical transmissivity of the melt.
