The kinetics of formation of an iron‐zircon pink color were studied by X‐ray diffraction. The iron reacts with the zirconia at a temperature below the reaction temperature. The initial reaction is nucleation‐growth‐controlled. At higher percent conversion a change in mechanism occurs, probably becoming diffusion‐controlled. At any given reaction temperature, there is an apparent limiting percent conversion.
