Abstract
The processing of nanocrystalline yttria doped zirconia powder via dry forming routes has been
investigated via the granulation of the powder using spray freeze drying (SFD). Free-flowing and
crushable powders suitable for either die or isosatic pressing have been achieved via the combination of
SFD with additions of up to 2 vol% of Freon 11; the latter reducing the strength of the granules whilst
not affecting the powder flowability into the die. The approach has allowed relic-free green bodies of
up to 55% of theoretical density to be produced using pressures as low as 250 MPa.
