Effects of particle shapes on the kinetics of solid reactions

In the paper, the effects of powder particle shapes on the kinetics of solid reaction (K.S.R) and errors caused by the current methods based on spherical particle models have been studied. It has been found that particle shapes have significant effects on kinetics of the solid reaction (K.S.R). However it has now not been involved in the present kinetic equations as a factor. The ball models used by the present kinetic equation have led to great errors not only in determination of the reaction constants but also in judgement of reaction types. This is a problem that has not been much recognized and needs to be solved immediately.
