纳米AgCl粉体的室温固相制备技术研究

Preparation of AgCl Nanopowders by Solid-phase Reaction at Room Temperature

以KCl和AgNO3为原料,通过加入分散剂并采用其对产物层层包覆的方式对传统的室温固相反应进行改进,制备出纳米AgCl粉末,并通过TEM及XRD对颗粒进行了测试表征。结果表明:通过"包覆"式固相反应制备工艺获得的AgCl呈规则球形,立方晶型结构,分散性高,平均粒径约20 nm,较传统方法制备的颗粒更加均匀细小。

AgCl nanopowders were prepared by improved solid state reactions at room temperature with dispersant wrapping the production. Characteristics of the nanomaterials were characterized by TEM and XRD. The results showed that the particle sizes of AgCl were about 20nm with the shape of sphericity and the configuration of cubic crystal. The AgCl powders had smaller sizes and its distribution was more identical than the ones prepared by traditional method.
