Method for preparing AlN ceramic through 3D printing technology
The invention belongs to the technical field of ceramics, and relates to a method for preparing AlN ceramics by utilizing a 3D printing technology, which comprises the following steps: uniformly mixing raw materials including Al2O3, an organic matter precursor, a sintering aid and a hot melting material to obtain premixed slurry, and drying the premixed slurry; granulating the dried powder through an internal mixer and a granulator to obtain particles; printing the particulate matters into a green body with a required shape by utilizing a fused deposition modeling 3D printing technology; carrying out debonding treatment on the green body to obtain an Al2O3/C prefabricated body; carrying out nitrogen thermal reaction on the Al2O3/C preform in a nitrogen atmosphere to obtain an AlN ceramic green body; and sintering and densifying the AlN ceramic green body in a nitrogen atmosphere to obtain the AlN ceramic device. The method effectively solves the problems that at present, an AlN ceramic special-shaped part is difficult to machine, and complex shape preparation is difficult to achieve.
本发明属于陶瓷技术领域，涉及一种利用3D打印技术制备AlN陶瓷的方法，包括以下步骤：将包括Al2O3、有机物前驱体、烧结助剂、热熔性材料的原料混合均匀，得到预混浆料并进行烘干；将干燥后的粉料经过密炼机和造粒机造粒得到颗粒物；利用熔融沉积成型3D打印技术将颗粒物打印成所需形状的坯体；对所述坯体进行脱粘处理，得到Al2O3/C预制体；将所述Al2O3/C预制体在氮气气氛下进行氮热反应，得到AlN陶瓷坯体；将所述AlN陶瓷坯体在氮气气氛下进行烧结致密化，即可获得AlN陶瓷器件。该方法有效解决了现有目前AlN陶瓷异性件加工难、难以实现复杂形状制备等问题。
