Sintering Additive on the Pore Structure and Mechanical Properties of Si₃N₄ Ceramic Foam Produced by Protein Coagulation Casting

Abstract:

Silicon nitride (Si₃N₄) ceramic foam was prepared from water-based Si₃N₄ slurries via protein coagulation casting method with egg white protein as the foam agent. The open porosity of the as-fabricated ceramic foams was close to 80%, and the compressive strength was about 20 MPa. Further, the content of sintering additive on the phase composition, pore structure and pore size distribution were investigated. Results indicate that with the increasing of sintering aids, more windows appear on the wall of pore and the average size increases. Moreover, Pore size distribution of as-fabricated ceramic not only changes with sintering additive addition but also varies with pore size.
