Metalorganic and Microwave Processing of Eutectic Al2O3-ZrO2 Ceramics

Abstract

The spatial distribution and sintering activity of ZrO2 governs the microstructure evolution upon microwave sintering of alumina-zirconia ceramics. Using the same microwave sintering profile thermal runaway occurs, when ZrO2-powders with high specific surface area are employed, yielding ceramics with eutectic Al2O3-ZrO2 inclusions, whereas ZTA-type ceramics are obtained from low specific surface area powders. Microwave sintering yields ceramics with a higher density at a particular sintering temperature as compared to conventional sintering.
