The Study of Microwave and Electric Hybrid Sintering Process of AZO Target

الملخص EN

We simulated the microwave sintering of ZnO by 3D modelling.

A large-size Al-doped ZnO (AZO) green ceramic compact was prepared by slurry casting.

Through studying the microwave and electric hybrid sintering of the green compact, a relative density of up to 98.1% could be obtained by starting microwave heating at 1200°C and increasing the power 20 min later to 4 kW for an AZO ceramic target measuring 120 × 240 × 12 mm.

The resistivity of AZO targets sintered with microwave assistance was investigated.

The energy consumption of sintering could be greatly reduced by this heating method.

Until now, few studies have been reported on the microwave and electric hybrid sintering of large-size AZO ceramic targets.

This research can aid in developing sintering technology for large-size high-quality oxide ceramic targets.
