Kinetics of liquid penetration into bottom edge of cast tape

As a result, it was confirmed that the measured rate of liquid penetration into the tapes, which were prepared with various casting speeds, blade gaps and slurry concentrations, is mainly determined by the distribution of void sizes. The largest value of the penetration rate constant was obtained for the tape made of spherical particles followed by those manufactured with fibrous, blocky and flaky particles, as could be expected from the analysis of void size distributions. Penetration rates into layers of synthetic graphite particles were higher than in those made of natural particles possibly due to the difference in their contact angles.
