| 摘 要： | 选择溶胶-凝胶粉末静态成珠法,制得了(Li_2O)-Na_2O-B_2O_3-SiO_2系统中空玻璃珠。用红外吸收光谱研究了凝胶结构随热处理温度的变化。随温度升高,Si—O—C_2H_5、Si—OH键逐渐消失,而Si—O—B,B—O,Si—O键逐渐形成和增加。借助光学显微镜、扫描电子显微镜观察了玻璃珠的中空状态和表面形貌。并探讨了成珠方法、过程及珠密度的影响因素。

| Abstract: | The hollow glass sphere in Na_2O-B_2O_3-SiO_2 system was prepared at static state by gel powder via sol-gel process. Its structure was studied by IR spectra. The hollow state and surface morphology of glass sphere was observed by SEM and optical microscope. The form method, process and the effects of various factors on density of hollow glass sphere were discussed. |
