In solids one could find place where the atom should be, but missing. Such places are called vacancies. With increasing of temperature neighbor atom could jump on the vacancy, so vacancy will disappear in place where it was, but appear in the place, where atom was. This process is stochastic, so vacancy will move in random direction. Density of vacancies will change in time with accordance to diffusion equation.

Compare Interstitial and Vacancy Atomic mechanism for Diffusion?

(a) Compare interstitial and vacancy atomic mechanisms for diffusion. (b) Cite two reasons why interstitial diffusion is normally more rapid than vacancy diffusion. Solution (a) With vacancy diffusion, atomic motion is from one lattice site to an adjacent vacancy. Self-diffusion and the diffusion of substitutional impurities proceed via this mechanism. On the other hand, atomic motion is from interstitial site to adjacent interstitial site for the interstitial diffusion mechanism. (b) Interstitial diffusion is normally more rapid than vacancy diffusion because: (1) interstitial atoms, being smaller, are more mobile; and (2) the probability of an empty adjacent interstitial site is greater than for a vacancy adjacent to a host (or substitutional impurity) atom.


What is the difference between interstitial and vacancy diffusion?

The main difference is atoms that which are channelled through the diffusing process where the atoms stick to the molecular structure of a material this only happens in interstitial diffusion where in vacancy diffusion the atoms reppelled away hence the word vacancy.


What atomic lattice defect aids diffusion?

I think it would be a point defect because a vacancy in the lattice structure would allow another atom to take the place of the vacancy.

Can the intermixing of two solids be termed diffusion?

No, the intermixing of two solids cannot be termed diffusion in the classical sense, as diffusion specifically refers to the movement of particles from an area of higher concentration to one of lower concentration, typically in liquids or gases. In solids, the movement of atoms or molecules is much more restricted and occurs primarily through mechanisms like vacancy diffusion or grain boundary diffusion. While some degree of intermingling can occur in solids under certain conditions, such as high temperatures, it does not align with the traditional definition of diffusion.
