Rheological behavior and stability of their suspensions of Sialon bonded corundum refractories were investigated, Suspensions with 79vol% exhibit shear-thinning characteristic, especially in 10～100s~(-1), and satisfy gelcasting.

A Sialon/corundum multiphase refractory was synthesized directly using silicon powder, aluminum powder and black corundum as starting materials.
