摘要
分析了热处理法去除ＭｏｎｇＨｓｕ红宝石紫色调及蓝紫色核心的原理，采用氧化还原作用，通过气体扩散和过渡元素的迁移，达到消除由钛造成的蓝紫色调和铁、钛电荷转移造成的蓝色调的目的，去掉黑心，使ＭｏｎｇＨｓｕ红宝石得到改善。
The article analyses the principle of removing violet hue and blue-violet cores of Mong Hsu rebies by heating treatment Making use of oxidization-reduction actions, by gas diffusion and movement of transitional elements, gets the end of removing blue-violet hue which is produced by titanium and blue hue which is produced by the intervalence charge transfer mechanism of iron and titanium, to enhance the Mong Hsu rubies
