摘    要:影响非平衡态含Ti炉渣中钙钛矿相长大因素有两个,一个是析出过程中自身长大,另一个是由大颗粒吞并小颗粒而产生的粗化。通过对非平衡态含Ti炉渣中钙钛矿相的析出长大研究,给出了描述非平衡态下由扩散控制弥散钙钛矿晶粒长大的动力学模型。

关 键 词:炉渣  钙钛矿  粗化  转变分数  晶粒长大

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.
Keywords:blast furnace slag  perovskite phase  coarsing  transformed fraction
