摘要
本文应用X射线衍射法定量测定V_2O_5晶相在γ-Al_2O_3上自发分散量随焙烧时间的变化,提出V_2O_5在γ-Al_2O_3上的自发分散动力学方程为:C_0-C=Bln(τ+1)+△C_1,并且说明在自发分散初期存在一快速分散过程。
Dependence of the residual crystalline V_2O_5on the surface of γ-Al_2O_3on heating time has been studied by XRD and suggested that the integrated rate equation of spontaneous dispersion of V_2O_5 on the surface of γ-Al_2O_3 is Co-C=BLn(τ+1)+△ C_1 and explained that dispersing quickly was Happened at the beginning in the heating process.
