摘要
The microstructure and properties of ZTM ceramics fabricated from spray-dried powders with differ granule morphology and deformability were determined. The effects of solid content of feed slurry on the granule character were discussed. Lower solid content results in hard and tough 'donut'-shaped granules resisted deformation during compaction. The microphotograph shows that relative large intergranular pores are major strength-limiting defects in fired material studied. The incomplete deformed granules are kept during sintering. Sintered material pressed from uniform and deformable granules produced from high solid content slurry has a homogeneous microstructure and relative high mean strength.
