摘要
气泡是蓝宝石晶体中的主要缺陷之一。本文中研究了采用泡生法生长蓝宝石晶体中气泡的俘获机理以及在晶体中的分布情况。研究结果表明气泡的分布与温场的结构相关,气泡产生的直接原因是结晶前沿较快的晶体生长速度。晶体中的气泡可以通过对生长速率的适当调整予以消除。
Bubbles are one of the most common known defects in sapphire ,crystals. The incorporation theory and the distribution of bubbles in sapphire crystal grown by the Kyropoulos method were studied. The results show that the distributions of the bubbles are closely related to the thermal filed structure, and the direct reason of the bubbles formation is the high crystal growth velocity in the crystallization interface. Bubbles in crystal can be eliminated through appropriately adjusting of growth velocity.
