testing surface

X-ray diffraction(XRD),transmission electron microscopy(TEM),BET surface area measurement and thermal analysis(TA)have been used to determine the characteristics of the nanopowdered silver prepared by chemical reduction with the polymolecular protectant.

用X -射线衍射、透射电镜 (TEM )、比表面测定和热分析 (TA)技术 ,对从高分子保护化学还原法制得的纳米Ag粉 ,做了相关的测定表征 ;从表观比热的测定结果探讨这一亚稳微晶体系在加热过程和热处理后所发生的各种变化。
