| Abstract: A method for producing ceramic articles with multiple distinct regions of
density by blending pore formers of different types or amounts with
ceramic particles to create multiple pore former/ceramic particle
mixtures. The mixtures are placed in a divided die cavity, divider
removed and subjected to compaction under pressure to produce a compacted
billet. The compacted billet is thermally processed to volatilize
organics from the billet and sinter the billet, creating a cohesive
billet of ceramic having two or more regions of density. |
