Surface properties of silver iodide

Abstract

IT is a rather curious fact that both low-energy and high-energy surfaces abound, but intermediate energy surfaces of high area are infrequently found and have been little studied. In a search of such intermediates, we recently examined the surface chemistry of silver iodide. One method is to compare the apparent water specific surface area to the nitrogen area. Another result which reflects the surface energy is the measurement of the heat of immersion in water and other liquids of particles of the solid sufficiently high in surface area to give meaningful results. © 1961 Nature Publishing Group.
