METHOD AND APPARATUS OF PREPARATION FOR EMERALD SINGLE CRYSTAL

摘要

The present invention is to control the crystal growth conditions such as V ₂ O ₆ -MoO ₃ / LiO ₂ flux and additive composition, crystal growth temperature, solubility of beryl by using a raw material of the composition such as natural beryl or natural beryl by controlling the emerald single crystal The present invention relates to a continuous emerald single crystal growth method and apparatus capable of arbitrarily and uniformly controlling the rate of color (green dopant) employment and crystal growth.;The emerald single crystal growth method is a three-zone horizontal temperature gradient flux reflux method that can grow an emerald single crystal having good green crystallinity with high crystal growth rate.
