摘要：

The effect of moisture content of granules on green and sintered bodies of alumina ceramics was studied. Alumina green bodies were formed from spray-dried granules containing 0.1-2.0% moisture at 50-350 MPa and sintered at 1600-degrees-C for 2h. Their microstructures were examined with an SEM and an optical microscope of transmission mode. The moisture content of granules significantly affected properties of green and sintered bodies. With increasing moisture content of granules, the density of green bodies increased. Fracture mode of green bodies changed from inter-granule to trans-granule. The Weibull modulus of sintered bodies increased with increasing moisture content of granules.
