Fabrication of high molar ratio K2O hollow glass microsphere for laser fusion research

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.
