研究认为，扩散处理合成蓝宝石中Fe2+和Ti4+离子的微观扩散迁移作用受控于表层空位迁移能、空位扩散系数及空位浓度梯度。
The research indicates that the micro-diffusion transference of Fe ~ ( 2 + ) and Ti ~ ( 4 + ) ions in the diffusion-treated synthetic sapphire is controlled by vacancy transference energy , vacancy diffusion coefficient and vacancy concentration gradient .

以焰熔法合成无色蓝宝石为基体、采用Fe和Ti化合物为渗色剂、在超高温条件下进行扩散处理的合成蓝宝石近期出现在国内外珠宝市场上。
A new type of synthetic sapphire with diffusion treatment has recently appeared on gem markets , which is treated from the flame fusion synthetic colourless sapphires by the diffusion with the compound of iron and titanium at super-high temperatures .
