Abstract
Herein, Al 2 O 3 –ZrO 2 multiphase ceramics with a eutectic molar ratio were prepared using the flash sintering technique at 1200 °C in 2 min. The samples were divided into two regions according to the microscopic morphology: multiphase ceramics zone and eutectic ceramics zone. The multiphase ceramics zone uniformly distributed irregular Al 2 O 3 and ZrO 2 phases. The eutectic zone presented typical eutectic morphology, where different morphologies of ZrO 2 was uniformly embedded in the Al 2 O 3 matrix, mainly showing fine lamellar, rod-like and irregular network morphology. Overall, flash sintering is a promising route to prepare high-performance multiphase ceramics.
