摘要
基于玻璃成分与性能之间的定量关系,以高强度、高化学稳定性、易熔和低粘度为目标,应用正交试验法对30种待选玻璃配方中Na2O、K2O、A l2O3、CaO的含量进行了优化,从中优选出了10种玻璃配方作为激光聚变实验靶用空心玻璃微球的候选配方。与国内外其它靶用空心微球玻璃的性能相比,候选配方的玻璃不仅化学稳定性和抗张强度有显著提高,而且各自的熔化温度、粘度等参数也满足空心玻璃微球炉内成球法的工艺要求。
Based on the quantitative relationships between glass composition and glass Young's modulus, density, chemical durability, viscosity, melting temperature, surface tension and devitrification, 10 glass compositions are selected as the optimum glass compositions of hollow glass microsphere used as ICF experiment target according to the requirements of high strength, high chemical durability, low melting temperature, low viscosity. Compared with the properties of other hollow glass microspheres for ICF experiment, the chemical durability of the 10 candidate glass compositions is improved significantly, and the tensile strength of the 10 candidates is also increased remarkably. Moreover, the melting temperature, soften point and viscosity of the 10 candidates still satisfactorily meet the requirements of HGM fabrication in tower furnace.
