Abstract
The pressure gradient naturally effected across the cake on pressure casting can lead to pore‐character gradients and dimensional distortion if the cake is significantly compressible. The compressibilities of cakes formed on pressure slip casting of aqueous Al2O3 slips defiocculated with an organic polyelectrolyte were determined for applied pressures ≤500 psi. In general the compressibility decreased with increasing pressure. Improved deflocculation of slips from which cakes were formed drastically reduced the level and pressure dependence of compressibility; cakes cast from well‐deflocculated slips were insignificantly compressible. Specific resistances determined concurrently agreed well with results obtained previously in kinetic studies. Compression‐permeability behavior can serve as a quality control test for the slip casting of technical ceramics.Keywords
