| 摘 要： | AgSt/AgCl composite grains were prepared by adding chloride ions to a mixed solvent in which silver stearate (AgSt) grains were dispersed under the condition of controlled pH value and characterized by SEM,XRD,UV and DSC.The results showed that AgSt/AgCl composite grains were composed of plate-like AgSt grains with small face-centered cubic AgCl particles formed on the surface of AgSt.UV spectra displayed a red shift of absorption for AgSt/AgCl relative to pure AgSt or AgCl.DSC showed a new thermal phase transition of AgSt/AgCl grains.
