Abstract
The I to or from II phase transition of ammonium chloride has been studied using energy-dispersive powder diffraction with a synchrotron source of X-radiation. The equilibrium transition temperature was found to be 184.5+or-0.5 degrees C and the activation energy for the transformation was found to be 213+or-15 kJ mol-1. The transition was satisfactorily described using the Avrami equation with a shape parameter of 3.
