Agglomerate and particle size effects on sintering yttria-stabilized zirconia

RHODES, W. H.·1981·Journal of the American Ceramic Society

Abstract

The initial‐, intermediate‐, and final‐stage sintering of fine crystallite yttria‐stabilized zirconia was studied. Experiments were conducted on powder lots of differing agglomerate size and one specially prepared agglomerate‐free powder. Initial‐stage sintering kinetics were compared with a sintering study on larger crystallite size calcia‐stabilized zirconia to access the Herring scaling law. It was found that agglomerates limit attainable green density, interfere with the development of microstructure, impede initial‐stage sintering kinetics, and limit the potential benefit of fine crystallites on final‐stage sintering. An gglomerate free powder centrifuge‐cast to 74% green density was sintered to 99.5% of theoretical density in a 1 h 1100°C cycle, which is ∼300°C lower than necessary for an agglomerated but equal crystallite size powder.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
