Preparation of Al2O3–ZrO2–SiO2 ceramic composites by high-gravity combustion synthesis
Source abstract
Abstract
Abstract By a furnace-free technique of high-gravity combustion synthesis, Al 2 O 3 –ZrO 2 –SiO 2 ceramic composites were prepared via melt solidification instead of conventional powder sintering. The solidification kinetics and microstructure evolution of the ceramic composites in high-gravity combustion synthesis were discussed. The phase assemblage of the ceramic composites depended on the chemical composition, where both (Al 2 O 3 + ZrO 2 ) and (mullite + ZrO 2 ) composites were obtained. The ceramic composites consisted of ultrafine eutectics and sometimes also large primary crystals. In the (mullite + ZrO 2 ) composites, two different morphologies and orientations were observed for the primary mullite crystals, and the volume fraction of mullite increased with increasing SiO 2 content. The ceramic composites exhibited a hardness of 11.2–14.8 GPa, depending on the chemical composition and phase assemblage.
