Diffusion in Solids: Heterodiffusion

This lecture covers the topic of heterodiffusion in solids, focusing on the diffusion of electrolytes in liquids and the diffusion of solutes in cubic crystals. The instructor explains the mechanisms of diffusion, including self-diffusion in metals and the diffusion coefficient. Various types of crystal structures and their impact on diffusion are discussed, along with the influence of temperature and pressure. The lecture also delves into the concept of infinite dilution heterodiffusion and the calculation of diffusion coefficients in different scenarios.
