Abstract
Method for making a ceramic mixture of boron and aluminum nitrides in the ratio of about 0.2 to 20 g atoms of aluminum per g atom of boron, and method for making shaped articles of the ceramic and of the intermediate from which the ceramic is prepared, comprising the steps (i) reacting a boron nitrogen compound with an organoaluminum compound in a suitable solvent to form a shapeable intermediate, and (ii) heating the intermediate at temperatures and under conditions to effect formation of the mixed nitrides.
