摘　　要：分别用"三步法"、"银铵溶液活化法"和"胶体钯法"三种工艺对空心玻璃微珠进行预处理后再镀银,并用扫描电镜(SEM)、能谱仪(EDS)等方法进行测试.实验结果表明,空心玻璃微珠经过"银铵溶液活化法"和"胶体钯法"预处理后再镀银,其银镀层银含量较高、镀层表面光滑、均匀.In this paper,the effect of pretreatment for hollow glass beads electroless silver plating was detailedly studied, including ＂Three-step method＂ , ＂Silver ammonium solution activation method＂and ＂Co loidal palladium method＂ three different pretreatment techniques. The silver plated hollow glass beads were investigated by scanning electron microscopy （SEM） and energy dispersion spectrometer （EDS）. The results showed that higher levels of silver content silver plated hollow glass beads with smooth and uniformcoating surfaces can be prepared by ＂Silver ammonium solution activation method＂ and ＂colloidal palladium method＂ pretreatment.
