【Abstract】 There are two factors that induence the mean growth rate of perovskite particles in the blast furnace slag bearing titania in non-equilibrium systems. One is the rate of nucleation and the variation of the fraction transformed to perovskite and the other is the coarsing arising from the growth of larger perovskite at the expense of smaller ones. In this paper, the kinetics of the isothermal growth of perovskite phase in the blast furnace slag was investigated, and a kinetical model of the growth of diffusion-limited perovskite particle in non-equilibrium systems was proposed.更多还原
