Drying of gelcast ceramics

OSTI ID:5811678
Plates (8.9 {times} 90.2 {times} 228.6 mm) of silicon nitride, sialon, and alumina made by gelcasting, a generic near-net-shape forming process, have been dried in a controlled humidity chamber. No constant-rate period was found in drying the gelcast plates. A linear shrinkage of 3--4% was observed, the shrinkage stopping after only about 20% of the total moisture had been lost. Dried parts, free of warpage and cracking, were obtained in reasonable times by controlling the humidity and temperature. 12 refs., 4 figs.
