Abstract: Microwave sintering is a new and highly active kind of singtering technology which is superior to the technology of traditional sintering. With highly pure AlN powders and without singtering additives, AlN transparent ceramics were obtained by using microwave sintering at 1700℃ for 2h. The result of experiments indicates that the AlN transparent ceramics prepared by this process have fine grain sizes (less than 10μm), uniform grain distribution, and no oxidized phrases. From above analysis, it is proved that AlN transparent ceramics can be sintered at low temperature by the microwave sintering technology.

Key words: microwave sintering, AlN, transparent ceramics, preparation
