Polygonization in Silver Chloride

Abstract

Jones and Mitchell¹ showed that etch pits were produced on surfaces of silver chloride crystals close to {100} by a 3 N solution of sodium thiosulphate, and demonstrated further that in many crystals (depending on the “precise crystallographic orientation of the surface and upon particular properties of individual crystals”) there was a one-to-one correspondence between the etch pits and dislocation lines emerging at the surface. This technique has been used here to examine the dislocation arrangement in bent single crystals of silver chloride grown from the melt.
