Research results are presented on the corundum structure transformation caused by reducing annealing. The annealing at 1500-2000°C in Ar atmosphere at CO + H₂ concentration 0.1-10 vol.% and N₂ 0.1-0.4 vol.% has been found to result in the corundum transformation into aluminum oxynitride compounds wi...
