高钾空心玻璃微球的制备
Fabrication of high molar ratio K2O hollow glass microsphere for laser fusion research
-
摘要: 以无机化合物为初始原料，选择合理的玻璃溶液配方和成球条件，用液滴法制备出直径200 μm，壁厚2 μm，K2O摩尔分数大于10 %的空心玻璃微球（HGM）。利用扫描电镜X射线能量色谱仪对玻璃球壳的组分进行了分析。结果表明，所制备的高钾空心玻璃微球各项技术指标能基本满足神光-Ⅱ物理实验的要求，微球球壳成份实测结果与理论计算结果吻合。

Abstract: With inorganic compounds, hollow glass microsphere (HGM) of above 10% molar ratio K2O was prepared by liquid-droplet method.The glass forming oxides content in solutions and technical conditions of preparing were optimized and selected. The molar ratios of glass forming oxides in shell of HGM were analyzed by means of EDAX device.The results showed that the diameter, wall thickness, concentricity and sphericity of HGM satisfied the physical experiments on the SG II device.Test value of molar ratio of glass forming oxides in HGM were closed to theoretic value.-
