High-Pressure Polymorphs in the Silver Iodide Phase Diagram

Abstract

A good x-ray diffraction pattern has been obtained for the new phase of silver iodide stable in the vicinity of 3 kilobars at room temperature. A stability diagram of the six phases of silver iodide is presented to show the probable position of the narrow stability field of this phase. The x-ray diffraction data indicate that the cell symmetry of the new phase is probably orthorhombic.
