Abstract<\/h2>\n\n\n\n

Al2<\/sub>O3<\/sub>\u00a0is inherently challenging to flash sinter due to its highly insulating nature. In contrast, TiO2<\/sub>\u00a0can be flash sintered readily due to its better electrical and ionic conductivity at elevated temperatures than those of Al2<\/sub>O3<\/sub>. In this study, two-phase composites of Al2<\/sub>O3<\/sub>-TiO\u2082 with various molar ratios (i.e., 34 mol.% Al2<\/sub>O3<\/sub>\/66 mol.% TiO2<\/sub>\u00a0and 20 mol.% Al2<\/sub>O3<\/sub>\/80 mol.% TiO2<\/sub>) have been successfully processed by flash sintering and a systematic flash sintering map has been constructed to explore the relationship between electric field (ranging from 300 to 1600 V\/cm) and the flash sintering temperature in Al2<\/sub>O3<\/sub>-TiO\u2082 composites. The map clearly demonstrates that the flash sintering temperature of composites decreases with increasing electric field or higher TiO2<\/sub>\u00a0molar ratio. The potential mechanisms of phase boundary assisted flash sintering are discussed. This study confirms that the appropriate design of two-phase composites can prominently promote the flash sintering of insulating ceramic materials.<\/p>\n","protected":false},"excerpt":{"rendered":"
