Abstract

A recently developed gel casting system based on water soluble epoxy resin was successfully applied to sialon ceramics. The solids loading could reach 48.9% without any pH adjustment, and all slurries exhibited shear-thinning behaviour. Flexural strengths of sialon ceramic obtained from 44.5 vol% slurry were 295.2 MPa at room temperature and 281.4 MPa at 700 °C; the microhardness was 16.5 GPa. The net-shape manufacturing of sialon ceramics could benefit from this investigation.
