Silicon-based porous structural ceramics: silicon nitride(Si3N4),SiAlON,Si3N4/SiC nanocomposites,are fabricated by various techniques.Pressureless sintering,partial hot-pressing(PHP),restrained sintering by reaction bonding(RSRB)were used to obtain porous ceramics with a fine pore size and good properties by tailoring the composition,microstructure and sintering condition.The porous Si3N4 ceramics have a high strength,toughness and strain tolerance,and the porous SiAlON ceramics has a good corrosion resistance.
