Abstract：The results of micro-infrared spectra and LA-ICP-MS research of growthzones in sapphire showed that there was an internal relationship between the formationof color of growth zone and —OH content in sapphire. In the sapphire which contained hexagonal growth zones, the content of —OH was similar in the same zone and varied from zone to zone. The content of —OH decreased gradually from dark growth zone to light growth zone. The content of —OH depended on the content of trace element Ti in the zones, which suggested that the content of —OH in the growth zones could be used to reflect the change rules of the formation process of sapphire. In the higher hydrogen condition, more Ti4+/Fe2+ substituted Al3+ into the sapphire crystal lattice. Otherwise, less or no Ti4+/Fe2+ substituted Al3+ into the sapphire crystal lattice. Therefore, systematic research of the distribution characteristic of —OH in the sapphire will be conducive to the formation mechanism of color of sapphire and provide new scientific ideas for high quality sapphire synthesis and optimization.
