Summary

SiC/Al2O3 nanocomposites were produced by combining Nyacol,® and colloidal Al2O3 with polysilastyrene (PSS) to produce a sol which was subsequently aged and fired in an inert atmosphere. The fired composites exhibited enhanced mechanical properties due to the interaction of the two-phase system. Both hardness and density were enhanced by the addition of PSS to colloidal Al2O3. The fired composites were characterized as to composition, microhardness, density and microstructures.
