SHS-Metallurgy methods were used to obtain samples in the form of aluminum oxynitride Al5O6N ingots (AlON) using mixtures of the thermit type. The experiments were performed in SHS reactors at initial nitrogen pressure 5 MPa. The optimal conditions for the synthesis of the most stable phase of aluminum oxynitride Al5O6N were determined. Regimes were developed for comminuting the synthesized ingots into powder with definite fractions. Spark plasma sintering (SPS) was used to obtain from them experimental samples with high density, hardness, and transparency.
