Abstract: A process for forming articles from inorganic sinterable particulates includes providing a well-dispersed, low pressure injectable slurry, freeze-forming the slurry into a desired geometry, and drying the piece so formed by a predominantly sublimative process, to produce a green article that can be conventionally sintered. The slurries preferably have a solids content of at least about 35 v/o, a viscosity of preferably not more than about 1000 cP at 100 s , and are preferably injectable at not more than about 1000 psi.
