Synthesis of aluminum oxynitride (AlON) and study of the properties of ceramics based on it

Аннотация

Aluminum oxynitride Al₂₃O₂₇N₅ was synthesized by solid phase synthesis from a stoichiometric mixture of aluminum nitride and aluminum hydroxide at 1850°C in a nitrogen atmosphere. Aluminum oxynitride ceramic was prepared from the synthesized powders by hot pressing without sintering additives. The obtained samples were characterized by scanning electron microscopy and X-ray phase analysis; the mechanical properties of the ceramic samples were measured.
