Abstract

The possibility of using aqueous poly(vinyl alcohol) solutions as surface-active, rheological, and sticking additives to obtain aluminosilicate ceramic suspensions involved in the production of high-porosity cellular materials (open-cell foams) was studied. It is established that aluminosilicate ceramic suspensions containing 0.5–1.0% PVA additive exhibit a drop in viscosity. This increases the critical concentration for structure formation and allows slips with a high filling coefficient to be obtained. Slip compositions for fabrication of open-cell foamed porcelain were developed.
