摘要
为实现对干凝胶法空心玻璃微球(HGM)渗透性能的有效调控,研究了初始玻璃配方、载气成分、精炼温度、精炼区长度、HGM壁厚对HGM渗透性能的影响。结果表明:当精炼温度低于1400 ℃时,初始玻璃配方对HGM渗透性能有显著影响。但是,随着精炼温度的升高和精炼区长度的延长,液态玻璃中碱金属氧化物的挥发比例逐渐增大,由不同初始玻璃配方制备的HGM对氘气的渗透性能逐渐趋近于相同。随着载气中氦气体积分数的降低或HGM壁厚的增大,室温下HGM对氘气的渗透系数逐渐减小。
Abstract
To investigate the deuterium permeation properties of hollow glass microspheres (HGMs) for inertial confinement fusion (ICF) targets, HGMs with different initial glass composition were fabricated by dried gel method under different atmosphere compositions in the furnace, temperatures, and lengths of refining zone. The permeability of HGMs with different wall-thicknesses to deuterium gas under ambient condition was tested. The results show that when the refining temperature is lower than 1400℃, the initial glass composition has notable effects on the deuterium-gas permeability of HGMs. However, the volatilization rates of alkali oxides in liquid glass bubbles increase with the temperature and the length of the refining zone, consequently, the permeability coefficients of HGMs made with different initial glass compositions increase and gradually approach to that of silica glass. With the total gas pressure unchanged, increasing the volume ratio of helium gas to argon gas in the furnace can enhance the permeability of HGMs. The permeability coefficient of HGMs to deuterium gas decreases with the increasing of the HGMs’ wall thickness.
