Mechanical Properties of ZrO₂–LaMgAl₁₁O₁₉ Ceramics

Abstract:

ZrO₂ ceramics have been widely used to many fields with its excellent physical and chemical properties, but the mechanical properties of YSZ ceramics, especially the fracture toughness, decline caused by the failure of the phase transformation toughening at high temperature. In this investigation, plate-like LaMgAl₁₁O₁₉ toughened ZrO₂ ceramics were prepared by pressureless sintering at 1550 °C for 3h in air . The bulk density of the sintered samples are between 5.5 to 6.0 g/cm³, and the relative density are above 93%. The mechanical properties of the ZrO₂-LaMgAl₁₁O₁₉ ceramics were studied systematically at room temperature. The flexure strength and fracture toughness of ZrO₂-LaMgAl₁₁O₁₉ ceramic are 811.8 MPa and 13.9 MPa•m^½ with the LMA addition of 2wt%.
