Preparation and Characterization of a Composite of Silver Iodide and Synthetic Mordenite

A composite material made up of AgI and the potassium form of mordenite has been prepared by treating the silver form of synthetic mordenite with potassium iodide. The composite as well as the silver and potassium forms of mordenite have been characterised by X-ray powder diffractometry, X-ray photoelectron spectroscopy, EDS analyses and ac conductivity measurements. It has been inferred that, in the composite material, AgI grows at the entrance of the zeolite channels without forming a continuous conducting phase. The silver form of mordenite has been proved to be a silver ion conductor by dc conductivity measurements.
