| 摘 要： | 本文首先利用正交试验确定了液相沉淀法合成纳米AgO粉体的最佳制备条件。接着研究了最佳条件下制备的纳米AgO粉体的性能。UV—vis DRS分析结果表明，反射率随着AgO含量的增加而降低，高纯度AgO在400nm-1100nm波长范围内具有较强的吸收能力。TG—DTG分析结果表明，在N2气氛下，AgO热分解为Ag2O。的温度范围为100℃—200℃，Ag2O热分解为Ag的温度范围为400℃-450℃。

Optical and Thermal Decomposition Performance for nano-sized Sflver（I,III）oxide Prepared - by Chemical Deposition Method with Orthogonal Experiments |

| Abstract: | In this paper, the nano-sized silver （I, III） oxide was prepared by chemical deposition method with orthogonal Experiments. Then the prepared samples were characterized. In the UV-vis DRS spectrum,the reflectivity decreased with the increment of AgO purity, and it showed that high content of AgO was with high absorption rate in the 400-1100nm wavelength range. According to the result of TG-DTG test,the transformation temperature range of AgO to Ag20 was from 100℃ to 200℃, and that of Ag20 to Ag was from 400℃ to 450℃ in nitrogen atmosphere. |
