| Abstract Scope |
The stability of bubbles and the microstructures of sintered Si<SUB>3</SUB>N<SUB>4</SUB> ceramic foams produced by direct foaming method were investigated. The purpose of the present investigation is to prepare Si<SUB>3</SUB>N<SUB>4</SUB> porous ceramics by particle-stabilized foams, the key feature of particle-stabilized foams is the use of short-chain amphiphiles. High gas-pressure sintering is conducive to the development of the whisker-like microstructures in Si<SUB>3</SUB>N<SUB>4</SUB> ceramic foams. The sintered Si<SUB>3</SUB>N<SUB>4</SUB> ceramic foams with the whisker-like microstructure will be quite promising for improving the mechanical strength of the ceramics by a simple and safe way. |
