The synthesis and characterization of porous silicon nitride/ silicon carbide nanocomposites have been studied.Porous Si 3 N 4 /SiC nanocomposites with 30 and 60 vol.%SiC were fabricated by two sintering steps of the mixture powder of Si 3 N 4 , carbon, and yttria Y 2 O 3 .The powder mixtures were uniaxially pressed using 25 MPa and sintered in nitrogen gas at 1650, 1750, and 1850 o C for 1, 2, an...
