Notes:
Composites consisting of a Ce-TZP matrix and in-situ grown particles of La(Fe,Al)12O19 were prepared by the solid-state reaction of Ce-TZP, La(Fe,Al)O3, and Al2O3 powders. The in-situ formation process of La(Fe,Al)12O19 in a Ce-TZP matrix was investigated in relation to the microstructure evolution. The Ce-TZP-La(Fe,Al)12O19 composites had significant magnetic properties and improved mechanical properties. The maximum value of magnetization of the Ce-TZP-La(Fe,Al)12O19 composites was obtained at 90 mol% LaFe12O19 in La(Fe,Al)12O19. The value of the three-point bending strength of Ce-TZP-20 wt% La(Fe,Al)12O19 (90 mol% LaFe12O19) sintered at 1350°C was 780 MPa, compared with 500 MPa of Ce-TZP ceramics. The composite demonstrated crack sensing based upon the change in magnetic gradient.
