doi:10.7517/j.issn.1674-0475.1992.03.243

Abstract

Abstract: Three monodispersed tetradecahedra AgBr (Ⅰ) host grains were prepared by microcomputer-controlled balance double-jet method at the condition of various pAg values. After that three monodispersed epitaxial AgCl/AgBr (Ⅰ) cubic emulsion grains also were prepared successfully by epitaxial deposition of AgCl on (Ⅲ) surface of host grains. The dielectric loss curres of epitaxial grains showed two separative peaks corresponding to the contributions of ionic conductivities of AgBr (Ⅰ) and AgCl. Both host and epitaxial grains, their ionic conductivities varied differently with pAg values.

Key words: epitaxial emulsion, dielectric loss, ionic conductivity
