摘要
马达加斯加是现今世界上最重要的蓝宝石产地，以马达加斯加低品质蓝宝石为研究对象，运用紫外一可见光（UV-Vis）吸收光谱和x射线荧光光谱（XRF）分析其颜色成因并对热处理工艺进行探索。敞口环境下，经1300℃～1600℃，12～20h热处理，多数样品Fe2＋／Ti4＋荷移减弱，深蓝色调变浅，部分样品Fe3＋含量减少、Ti4＋含量增加，显示出纯正的蓝色。
Abstract Madagascar is now the most important origin of sapphire all over the world. Aiming to analyze thecoloration mechanism with ultraviolet-visible absorption spectrum and X-ray fluorescence （XRF） and to explore the heat treatment process of low quality sapphires from Madagascar, the sapphire samples are treated at 1300 ℃- 1600 ℃ for 12-20 h in the air, most of the samples become light ones with weaker Fe2＋/Ti4＋ charge transfer, and some samples show fine color in blue with the decline of Fe3. and increase of Ti4＋.
