Creep and strength of ZrP2O7 bonded Si3N4 porous ceramics at 800-1000 °C

The creep behavior and bending strength of 25 wt.% ZrP2O7 bonded Si3N4 porous ceramics at 800-1000 °C are investigated. The creep test results reveal an extensive primary creep response and the stress exponent values n is 5.38. The bending strength is as high as 102.1 MPa even at 800 °C.
