| Abstract: | α–Al2O3–3YSZ porous ceramics were fabricated using the slip casting method with the incorporation of 15 wt% of submicron Al2O3 powders as sintering additives. The materials were prepared by solution combustion synthesis using glycine or urea as fuels. Following firing of the ceramics at 1550°C, the percentage of closed porosity was found to be in the range from 14.1 to 24.0%. The experimental results revealed a linear correlation between density and closed porosity of Al2O3–3YSZ corundum ceramics. Ceramic samples that underwent firing at 1550°C exhibited relative density values ranging from 75 to 85%, accompanied by an open porosity of 0.90 to 1.71%. The findings indicate that the morphology of the used aluminum oxide additives synthesized through combustion exerts a predominant influence on the strength characteristics. [ABSTRACT FROM AUTHOR] |
