Beschreibung
Zusammenfassung:	The invention discloses a preparation method of AlON ceramic powder based on 3D printing forming, which comprises the following steps: (1) mixing raw material powder, a solvent and an additive to prepare raw material ink with high solid content, (2) printing the raw material ink into a raw material green body with a regular three-dimensional through hole structure by adopting a 3D printing formingprocess, and drying the raw material green body, (3) putting the raw material blank into a reaction device with airflow control and anti-pollution functions in a high-temperature graphite sintering furnace, and carrying out high-temperature synthesis in a controlled reaction environment, and (4) finally, carrying out ball-milling process treatment to obtain the high-purity AlON ceramic powder. Bymeans of the method, the raw material powder can be printed into a green body with a regular three-dimensional through hole structure, a gas-solid synthesis reaction can be fully carried out during high-temperature synthesis,
