Preferred Label : chemical diffusion;
IUPAC definition : diffusion under the influence of a gradient in chemical composition. In concentrated
solid solutions, e.g. A sub 1 i -x /i /sub B sub i x /i /sub , or in diffusion
couples, the motion of one constituent causes a counterflow of the other constituents(s)
or vacancies. In this case one can define a diffusion coefficient for the intermixing,
which is called the chemical diffusion coefficient or interdiffusion coefficient.;
