| 摘 要： | 采用高温扩散方法对一种低品质蓝宝石进行改善实验,改善后的成品为黑色蓝宝石.从样品特性、改善目的及高温扩散原理出发,选用Fe2O3、TiO2、Co2O3作为着色剂,硼砂、Na2CO3为助熔剂,Mg(OH)2为催化剂进行改善实验,设计了系统的改善工艺流程并取得了预期的效果.运用紫外-可见光吸收光谱、X射线荧光光谱及能谱对改善后的样品进行了测试,并分析了改善后低品质蓝宝石呈黑色的原因.

| Abstract: | High-temperature diffusion method is used to change the color of one kind of low-quality sapphire into black.Considering the sample's characteristic,diffusion theory and purpose,Fe2O3,TiO2 and Co2O3 are used to change sapphire's color,together with borax and Na2CO3 as fluxing agent,Mg(OH)2 as catalyst,then a systematic improving technique and process are designed and the results come out as expected.UV-VIS,XRF,and EDS spectra are used to test the samples after improving experiments,and the reason why this k... |
