摘　　要：山东蓝宝石主要产于山东潍坊地区的昌乐县和五图县,因含铁量高,多呈近于炭黑色的靛蓝色、绿色和褐黄色,因而影响其商业价值。本论文针对褐色系列的山东蓝宝石采用传统热处理和热扩散处理方法进行试验对比研究,认为热处理对改善山东蓝宝石的透明度有所帮助,但是不能产生理想的颜色,对其内部特征也无明显效果;而添加TiO2后进行扩散处理的样品可以得到较为理想的颜色,即蓝绿色到蓝色,且透明度和深色矿物包体得到改善。Shandong sapphire is mainly produced in Changle and Wutu of Weifang area, because of their high iron content, most of them are indigo blue, which is the color close to the carbon black, green and brown yellow, thus influence their commercial value. This thesis aimed at brown series of Shandong sapphire with traditional heat treatment and thermal diffusion treatment to have an experiment comparison research. The results showed that heat treatment was helpful to improve the transparency of Shandong sapphire, but couldn＇t produce the ideal color, and it also had no obvious effect on its internal features. However, samples＇ diffusion treatment after adding TiO2 could get comparatively ideal color, which is blue-green to blue. And transparency and dark mineral inclusions were improved.
