“…The multilayered structure combines the small pore size of the top layer with the high permeability. The pressure drop caused by the multilayered substrate is usually neglected when studying layer growth rate during dip-coating (9,10). This paper studies the formation of the dip-coated layer on a two-layered substrate.…”

“…The granules in an aqueous medium are usually broken down into individual particles by mechanical means, such as ultrasonic dispersion. In such cases, there is another problem, in which the fine size particles in aqueous medium tend to form larger particles by agglomeration [2]. To prevent particle agglomeration, a suitable dispersant is often added to ceramic slurries.…”

Commercially available ceramic powders may contain granules due to limitation in the powder processing. Preparation of highly dispersed ceramic slurry from the powder requires pretreatment using mechanical agitation with sonification. Fine particle in aqueous medium also has another problem in which the fines tend to form larger particles by agglomeration. In this study, the influence of granules/agglomerates on filtration forming and sintering processing were examined. This study focused on zircon (ZrSiO 4 ) granules (<250−µm), which were subjected to mechanical agitation with sonification at pH 7 with and without dispersant, and both mechanical and chemical pretreatment at pH 11. A dependence of pretreatment in the behavior during filtration compaction and sintered densities was found. Highly dispersed ceramic slurry could be obtained by chemical pretreatment using a dispersant (tetra sodium pyrophosphate) at pH 11. The highly dispersed slurry led to producing of a high particle compaction during filtration forming and a high density of sintered sample.
