The effect of temperature on phases, density and fracture toughness K1C of SiAlON ceramics
View through CrossRef
In this study, the effects of temperature on phase formation, density, and fracture toughness (fracture toughness, K1C) of SiAlON ceramics were investigated. The synthesis conditions were optimized at 1650 oC for 4 hours in N2 environment at 1.0 MPa pressure. The temperature affected the phase composition, density, and fracture toughness, K1C of SiAlON ceramics. The optimal synthesis of SiAlON ceramics showed results: the high density of 3.21 g/cm3; the low water absorption of 0.20%; the porosity of 0.61% and the fracture toughness, K1C of 5.80 MPa.m1/2.
