摘要：
The theoretical analysis of Ostwald ripening for coarsening of a dispersion of particles by a second-order interfacial reaction at the particle-matrix interface revealed: in the case of a simple second-order interfacial reaction the mean particle size increases as t 1 3, the same as that for a diffusion controlled coarsening process. However, the stationary normalized particle size distribution has a large cut-off radius of 3, and is clearly distinguishable from the cases of pure diffusion controlled coarsening and first-order interfacial reaction controlled coarsening. © 1995.
