Low‐Temperature Sintering of Aluminum Oxide

Abstract

A fine‐sized (∼0.1 μm), agglomerate‐free Al 2 O 3 dispersion was used to prepare homogeneous green bodies with ∼69% relative density and ∼10‐nm median pore radius. Samples could be sintered at 1150°C to a relative density >99.5% and an average grain size of 0.25 μm.
