Abstract
Aluminum oxynitride or ALON is a crystal made of various amounts of aluminum oxide and aluminum nitride. The resulting material is nitrogen stabilized cubic aluminum oxide, which is a face-centered cubic with spinel structure. The lattice parameter of ALON varies from 7.938 to 7.951. This composition has a unit cell with lattice parameter of 0.7948 nm. ALON is termed as a “nonstoichiometric spinel” because some cation sites are occupied by vacancies. Neutron-diffraction studies confirm that oxygen and nitrogen occupy the anion sites of the spinel lattice; and that aluminum cations occupy both the octahedral and tetrahedral sites of the spinel structure. Neutron-diffraction studies confirm: (1) oxygen and nitrogen occupy the anion sites of the spinel lattice; (2) aluminum cations occupy both the octahedral and tetrahedral sites of the spinel (Fd3m) structure. Corbin essentially implies that the vacancies occur at the octahedral cation sites. ALON can be produced by a variety of methods, including: (1) reaction sintering of alumina and aluminum nitride, (2) simultaneous reduction and nitridation of alumina, (3) combustion like reaction of aluminum metal with oxygen and nitrogen, and (4) reaction of gases.
