Kinetics of first stage of formation magnetite nanoparticles prepared by chemical precipitation method

Abstract

First stage of formation magnetite nanoparticles is described by kinetics equation. Solution of kinetics equation is Gauss function. Mean value and standard deviation of Gauss function are , Critical size, determinant of collapse and growth of nanoparticles are determined. It's showed nanoparticles less critical size may be is collapsed, bigger - grow. The dependence of the size and speed of the growth size on time are determined. © 2009 IOP Publishing Ltd.
