ABSTRACT:
A method for making an alpha prime SiAlON-based ceramic article, including the steps of providing an admixture of starting materials and densifying said admixture. The admixture includes: beta silicon nitride; a source of aluminum selected from the group consisting of aluminum nitride, alumina, and mixtures thereof; at least one oxide compound; and a plurality of alpha prime SiAlON seeds.
