| 摘 要： | 在许多由固相反应生成合金和无机材料的生产过程中,扩散传质控制着反应的过程。但是,对扩散控制固相反应系统的机理和动力学研究还很不成熟。Jander首先把平面扩散抛物线方程用于球体内部的扩散过程,导出了Jander方程,由于平面扩散截面积不变和球体扩 |

| Abstract: | A spherical model for solid state reactions controlled by diffusion has been developed in this paper. Two equations between the conversion ratio and reaction time and temperature were derived from the model. The equations were tested by the solid state reaction of Synthesis of Si_3N_4 from silicon and nitrogen. The results show that the model is applicable for solid state reactions controlled by diffusion. |
