Abstract: | Aqueous gelcasting of alumina is optimised by preparing concentrated agarose solutions under overpressure conditions. The better dissolution reduces the viscosity and improves the microstructural control leading to green densities higher than 60% of TD. The enhancement of the green strength is not accompanied by a significant increase of the plastic behaviour during fracture for agarose contents < 1 wt.%. Sintered densities > 99% of theoretical are obtained. |
