摘　　要：为实现惯性约束聚变靶用空心玻璃微球的均匀掺杂,采用溶胶-凝胶技术结合炉内成球法,以钛酸四丁酯为掺杂剂,对钛掺杂玻璃溶胶-钛掺杂玻璃凝胶-钛掺杂干凝胶粒子-钛掺杂空心玻璃微球(Ti-HGM)这一掺钛空心玻璃微球的制备方法进行了探索。实验结果表明:掺钛效应使空心玻璃微球壁厚均匀性、同心度有所降低,但对壁厚、直径控制基本无影响;Ti与Si原子分数比为2.23%的Ti-HGM掺杂基本均匀,近70%微球的保气半寿命在一个月以上。A preparation method of the titanium doped hollow glass microsphere （Ti-HGM） was investigated, which uses tetrabutyl titanate （Ti（OC4 H9 ）4 ） as dopant and follows the sol-gel route of titanium doped glass sol-titanium doped glass gel- dried titanium doped gass gel particle-titanium doped hollow glass microsphere, in order to uniformly dope the hollow glass micro- sphere for inertial confinement fusion targets. The results show that the doping effect decreased the wall thickness uniformity and concentricity of Ti-HGMs, and had no influence on diameter and wall thickness. The Ti HGMs of Ti, Si atomic ratio of 2.23% were almost uniformly doped, and the gas-storage half life of nearly 70% Ti-HGMs was more than one month at room tempera- ture.
