Influence of pH on the pressure slip casting of silicon carbide bodies

The effect of interparticle forces and applied pressure on the kinetics of the pressure slip casting process, on cake compressibility, and on the green properties of the resulting silicon carbide bodies was investigated. The structure of particle aggregates in the suspensions was determined by electrophoretic measurements, particle size analysis, and rheological techniques. The relative green density, water content and pore size distributions of the consolidated bodies were measured and a good correlation found between the properties of the pressure cast bodies and the structure of the initial suspensions.
