| Abstract: | The formation of γ-AlON from Al2O3 and AlN was investigated as a function of some of the reaction parameters, that is, temperature and time. The appearance of phases was followed in conjunction with the change in lattice parameter to reveal the reaction sequences of formation. An oxygen-rich γ-AlON phase formed first, which reacted further with AlN. Nitrogen diffusion through the γ-AlON lattice seemed to be rate controlling. |
