The Study on the Production of Reaction Bonded Aluminum Oxide by Using Microwave Energy

ABSTRACT

By using homestyle microwave oven, Al-Al2O3 powder mixture could be oxidized and sintered into Al2O3 body. The differences in powder characteristics among the differently processed raw materials affect the oxidation and sintering behaviours, and these effects were more pronounced in case of microwave oven than of conventional furnace. Al-Al2O3 powder mixture was oxidized and sintered within 2hrs, which could save both processing time and energy.

Key words: Microwave, Low-shrinkage alumina, Oxidation of Al
