Interaction of ions in molten slag, salts and oxide compounds on diffusion
The diffusion of a ion in slag, salts and oxide compounds is influenced from other ions in the surroundings. The linear relations between the fluxes and the forces of ions are defined as the phenomenological equations. The proportional coefficients named as the transport coefficients represent the interaction of ions on diffusion. The transport coefficients between i ion and j ion are reciprocal and the relation is called as the Onsagers reciprocal theorem. The fluxes of ions are defined on a coordinate and one flux is not independent. The transport coefficients should be satisfied the entropy production on diffusion. The transport coefficients can be calculated from some of the transport properties such as electrical conductivity, transference numbers, tracer diffusivities, interdiffusivities. Others can be determined from the transport coefficients. The diagonal terms in the transport coefficients are positive and the other terms are positive or negative. The values of transport coefficients in some slag, salts and oxide compounds are examined from the non-equilibrium thermodynamics.
