Preparation and characterization of AgSt/AgCl composite grains
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.
