Tungsten Copper Electrode Infiltration Mechanism II

Spontaneous infiltration filled the porous tungsten matrix with molten copper solution by means of capillary force rather than the diffusion of atoms. Viewed from the mechanism of capillary, the gravitational potential energy of the capillary liquid should come from inside the liquid molecules into the adhesive layer for the loss of potential energy. Because the potential energy in the adhesion layer should be smaller than in the liquid inside, according to the potential energy minimum principle in stable equilibrium, the molecules inside the liquid have to squeeze into the adhesive layer so that the adhesive layer has a tendency to stretch.

The potential higher copper solution continuously into the inner molecular layer attached to the lower potential, the molecules will keep the potential loss of gravitational potential energy is converted into the molecule, so the liquid rising in the capillary.
