AlN ceramic powder preparation method based on 3D printing molding
The invention discloses an AlN ceramic powder preparation method based on 3D printing molding. The method 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 blank with a regular three-dimensional through hole structure by adopting a 3D printing molding process, and drying the raw material blank; (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 AlN ceramic powder. According to the method, the raw material powder can be printed into the blank with the regular three-dimensional through hole structure, the gas-solid synthesis reaction can be fully carried out during high-temperature synthesis, and the high-purity AlN ceramic powder can be obtained by combining the ceramic powder synthesis reaction device with airflow control and anti-pollution functions.
本发明公开了一种基于3D打印成型的AlN陶瓷粉体制备方法，包括如下步骤：(1)首先将原料粉体、溶剂和添加剂混合，制备成高固相含量的原料墨水；(2)然后采用3D打印成型工艺将原料墨水打印成具有规则三维通孔结构的原料坯体，并将原料坯体进行干燥；(3)再将原料坯体置于高温石墨烧结炉内具有气流控制和防污染功能的反应装置中，在受控的反应环境下进行高温合成；(4)最后经球磨工艺处理后，即可获得高纯度的AlN陶瓷粉体。本发明通过上述方法，可以把原料粉体打印成为具有规则三维通孔结构的坯体，有利于高温合成时气‑固合成反应的充分进行，再结合具有气流控制和防污染功能的陶瓷粉体合成反应装置，就能够获得高纯度的AlN陶瓷粉体。
