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。

Abstract: | A preparation method of the titanium doped hollow glass microsphere (Ti-HGM) was investigated, which uses tetrabutyl titanate (Ti(OC4H9)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 microsphere 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 temperature. |
