ABSTRACT:
Aluminum oxynitride is prepared by the pyrolysis of an organosiloxydihaloalane such as trimethylsiloxydichloroalane in the presence of a nitrogen-containing atmosphere. The organosiloxydihaloalane may conveniently be prepared by reacting together an aluminum halide and at least one disiloxane.
