Abstract
The seeded gel sintered to 98% of theoretical density after 100 min at 1200 degree C, whereas the unseeded gel had to be sintered at 1600 degree C to reach 94% of theoretical density. This difference results primarily from nucleation by the alpha -alumina seeds and enhanced transformation of the boehmite to alpha -alumina, such that a uniform, well-ordered, fine-grained alpha -alumina microstructure forms prior to densification.
