| 摘 要： | 明溪天然蓝宝石主要呈色元素为Fe和Ti，颜色常带有黄、绿或紫色调，颜色不纯正。在温度为1300℃，环境为氩气气氛中进行热处理后，可消除蓝宝石中原来存在的杂色调，使颜色向纯蓝色方向变化。本文还对热处理后蓝宝石的光吸收港及颜色变化机理进行了初步探讨。

| Abstract: | The main coloring elements in Mingxi natural sapphire are Fe and Ti. It often shows amixed color (yellow, green and purple hues ). After heat treatment in argon atmosphere at 1300C,the mixed hues except blue can be eliminated, leading to the color alteration of natural sapphire toa pure blue color. The color alteration mechanism and absorption spectra of sapphire after heattreatment are also briefly discussed in this paper. |
