| 摘 要： | 晶体宏观形态和表面微形貌特征是晶体生长机制的具体反映,通过对晶体形貌特征的研究,探寻晶体生长的规律,为进一步改善晶体的质量打下基础。通过对水热法KTP晶体(磷酸钛氧钾,KT iOPO4,KTP)宏观形态和表面微形貌的研究,首次发现了KTP晶体中高指数晶面和{100}单形晶面上的螺旋生长纹,探讨发现高指数晶面和{100}单形晶面上螺旋纹的形成原因主要是溶液的过饱和度偏低以及籽晶的悬挂方式,为生长高质量的KTP晶体,提出了增大原材料溶解区与晶体生长区的温度差、改变籽晶的切向和悬挂方向等建议。

| Abstract: | 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. |
