The increasing loadage led to the decreasing of self - decomposition and the size of silver particles could be adjusted 用hrtem观察粉体形貌， x一射线衍射分析物相组成。
2.
The weight gain of powders could be slightly increased with the increasing ph value , formaldehyde dosage and powder loadage , but the most utilization ratio of silver was only 35 . 2 percent . the composite powders with the silver content between 13 % ~ 70 % were produced 尽管提高ph值、甲醛量及粉体的装载量能在一定程度上增加化学镀后粉体增重即银的析出量，但远低于理论析出值，银的最大利用率仅为35 . 2 。
