Cold isostatic pressing (CIP) is often used in the compaction of nano-sized powders. For technological reasons, however, uniaxial pressing prior to CIP takes place. This Paper reveals the first quantitative measurements of density gradients within and the Asymmetric sintering response of nanoscale zirconia compacts formed by (I) simple Uniaxial compaction and (ii) specific ratio of uniaxial and CIP pressure.
