Abstract
Solid-state sintered silicon carbide (SiC) ceramics with respectable performance were successfully prepared with a gel casting method. Only acrylic resins were used as dispersants to form a thermally gellable SiC ceramic slurry with reasonable solid load of 45 vol%. The effect of the dispersants and solid load on the stability and rheological behaviour of the SiC suspensions has been systematically discussed. It has been established that the sintering performance, microstructure and mechanical properties of SiC ceramics are significantly affected by the rheology behaviour of the SiC suspensions. Finally, sintered samples with a relative density of 95.16 % (3.05 g/cm3) and a flexural strength of 377.4 MPa were achieved with the gel casting method.
