离子注入技术在山东蓝宝石优化处理中的应用

Application of Ion Implantation Technique in Optimization Treatment of Shandong Sapphire

本文报道了用离子(Be2+和Ti4+)注入技术优化处理山东蓝宝石的工作。对处理前后样品一系列测试和实验的结果表明:(1)样品经过离子注入处理后,表面光泽明显增强,表面光洁度保持良好;(2)山东蓝宝石注入Be2+后,颜色较处理前更深,说明Be2+虽然不是致色离子,但可对蓝宝石颜色产生明显的影响;(3)注入Ti4+后,山东蓝宝石的颜色变浅变艳了。进一步证明了山东蓝宝石的颜色深是由于Fe2+浓度高,同时Ti4+浓度相对太低所致,对今后山东蓝宝石乃至其它宝石的优化处理提供了新的思路和方法。

The paper reports the technique using ion implantation （Be^2＋ and Ti^4＋） technique in the Shandong sapphire treatment. Some testing and research had been done before and after the implantation. The results show that ： （ 1 ） As ion was implanted in, the luster turned obviously brighter. While surface of the samples kept smooth as well as before ; （2） As Be^2 ＋ was implanted in Shandong sapphire, the color turned obviously heavier, though Be^2＋ was not color-causing element, it could affect the color; （ 3 ） As Ti^4＋ was implanted in, the color of Shandong sapphire turned fade and brighter, which indicated that the dark color was because of high proportion of Fe^2＋ while low proportion of Ti^4＋. It is a new method of optimization and treatment in Shandong sapphire and other gems.
