Growth kinetics of nanoshells of the intermediate phase with allowance for finite reaction rates at interphase boundaries

Growth kinetics of the intermediate phase upon reaction diffusion in core-shell systems with simultaneous allowance for barriers at interphase boundaries, curvature, and concentration dependence of the interdiffusion coefficient inside the phase has been analyzed. It has been shown that the throughput capacity of interphase boundaries can change in the process of growth of the phase (both monotonically and nonmonotonically) and the concentration-range width of the phase likewise changes in a nonmonotonic manner.
