Abstract: An aluminum-nitrogen polymer is prepared by reacting an organic nitrile with a dialkylaluminum hydride to form an organoaluminum imine, and heating the imine to a temperature of 50 ° to 200 °C. The polymeric product can be subjected to an additional heat treatment to form a more highly cross-linked polymer. After either heat treatment the polymeric product can be further reacted with a primary amine or ammonia. The organoaluminum imine as well as the aminated or nonaminated polymers can be pyrolyzed in a nonoxidizing atmosphere to form an aluminum nitride-containing ceramic.

Abstract: SiC/AlN ceramics are produced by dispersing elemental silicon powder in a ceramic precursor polymer containing Al, N, and C atoms, and heating to cause a reaction between the elemental silicon and the polymer to produce an amorphous char containing carbon-silicon bonds and aluminum-nitrogen bonds. The amorphous char can be further heated to a temperature sufficient to crystallize the char to a SiC-AlN ceramic.

Abstract: A block copolymer is prepared by reacting an aluminum-nitrogen polymer and a silazane polymer at a temperature not greater than 400°C. Block copolymers containing alkenyl or alkynyl groups can be crosslinked by supplying energy to generate free radicals. An AlN/SiC-containing ceramic is formed by pyrolyzing the crosslinked block copolymer in a nonoxidizing atmosphere.
