摘要
Abstract
High- temperature diffusion method had been used to design an improving technique with a foundation of twice heat - treatment to change low - quality corundum into black sapphire.With the optimum temperature, the reagent pretreatment and adding effective flux, low -quality corundum had been changed into black sapphire. EDS spectra and UV -VIS spectra had been used to test the samples. The analysis showed that the mechanism of color enhancement is adding Fe3 +as well as Fe2+ and Ti4+ to inhibit absorption by each other as to make sample totally black. And it also showed that heating temperature and concentration gradient of coloring ions are main factors for diffusion.关键词
