ABSTRACT:
Process for producing ceramic compositions by dispersing elemental silicon powder in a ceramic precursor polymer containing Al, N, and C, shaping the resultant composition, and heating the shaped product to cause a reaction between the elemental silicon and the polymer to result in an intermediate composition and further heating the intermediate composition to a temperature sufficient to consolidate the char to a dense SiC--AlN solid-solution or microscopic ceramic.
