摘　　要：在室温条件下,分别以硝酸银和氯化钠为银源与氯源,采用直接化学沉淀法进行合成,获得了稳定的氯化银粉末。采用X射线衍射(XRD)和透射电镜(TEM)分析测试技术对氯化银粉末物相和微观结构进行表征,实验结果表明,合成的样品均为氯化银,无单质银存在,并且氯化银颗粒平均尺寸为110nm左右。Silver chloride was synthesized under room temperature condition by adopting a simple and generic approach of the direct precipitation method,using silver nitrate and sodium chloride as raw materials,respectively.Stable silver chloride AgCl powders was obtained.The prepared sample was characterized for the phase and microstructure analysis by XRD and TEM.The results showed that the samples were completely composed of AgCl with no elemental silver existence,and the as synthesized sample showed a uniform morphology with an average particle size of about 110 nm.
