We simulated the microwave sintering of ZnO by 3D modelling. A large-size Al-doped ZnO (AZO) green ceramic compact was\nprepared by slurry casting. Through studying the microwave and electric hybrid sintering of the green compact, a relative density of\nup to 98.1% could be obtained by starting microwave heating at 1200âË?Ë?C and increasing the power 20 min later to 4kW for an AZO\nceramic target measuring 120 Ã?â?? 240 Ã?â?? 12 mm. The resistivity of AZO targets sintered with microwave assistance was investigated.\nThe energy consumption of sintering could be greatly reduced by this heating method. Until now, few studies have been reported\non the microwave and electric hybrid sintering of large-size AZO ceramic targets. This research can aid in developing sintering\ntechnology for large-size high-quality oxide ceramic targets.
