Growth and Morphology of Hydrothermal KTP Crystal

The characteristics of crystal's macroscopic and micro morphology are mirrors of the mechanism of crystal growth.The study of macroscopic and micro morphology of the crystal is not only an aid to find the truth of the crystal growth,but also some help to improve the quality of the grown crystals.Some unusual crystal faces with large indices and the spiral growth striations on {100} in hydrothermal grown KTP crystal were reported and the causes were discussed,such as,lower concentration of supersaturated solution and the directions of seed crystal.Some suggestions on improving the technics of the crystal growth of KTP were given.
