Abstract

The densification behaviour of Sm₂Zr₂O₇/SmAlO₃ ceramic composites was studied by pressureless sintering at temperatures of 1500-1700^oC for 10 h in air. The microstructure and hardness of Sm₂Zr₂O₇/SmAlO₃ ceramic composites were investigated by the X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy and Vickers hardness tester. The Sm₂Zr₂O₇/SmAlO₃ ceramic composites are composed of pyrochlore-type Sm₂Zr₂O₇ and perovskite-like SmAlO3 structure. The relative density of Sm₂Zr₂O₇/SmAlO3 ceramic composites increases with increasing sintering temperature. Vickers hardness of Sm₂Zr₂O₇/SmAlO₃ ceramic composites slightly increases with increasing SmAlO₃ content.
