A Modified Effective Binary Diffusion Model

  title={A Modified Effective Binary Diffusion Model},
  author={Youxue Zhang},
Uphill diffusion, the diffusion of a component up its own concentration gradient, has often been observed in experimental studies of diffusion i synthetic multicomponent systems and natural silicate melts. To apply experimental data to natural processes, it is necessary toquantify this effect. A modified effective binary diffusion model is developed in this paper. The diffusive flux of a component is assumed tobe proportional to its activity gradient (instead of concentration gradient). The… CONTINUE READING
