Preparation method of high-strength aluminum nitride ceramic substrate
The invention belongs to the technical field of ceramic materials, and particularly discloses a preparation method of a high-strength aluminum nitride ceramic substrate. The preparation method of the high-strength aluminum nitride ceramic substrate comprises the following steps: (1) mixing modified aluminum nitride powder, a sintering aid and an organic solvent, carrying out primary ball milling for 12-24 hours, and drying to obtain powder; (2) mixing the powder obtained in the step (1), modified ethyl cellulose and a dispersing agent, carrying out secondary ball milling for 12-24 hours, and then vacuumizing and defoaming to obtain ceramic slurry; and (3) carrying out tape casting on the ceramic slurry obtained in the step (2) to obtain a green belt, and then slicing, laminating, degumming and sintering to obtain the high-strength aluminum nitride ceramic substrate. The prepared high-strength aluminum nitride ceramic substrate has good bending strength and fracture toughness, and popularization and application of the ceramic substrate are facilitated.
本申请属于陶瓷材料的技术领域，具体公开了一种高强度氮化铝陶瓷基板的制备方法。高强度氮化铝陶瓷基板的制备方法，包括如下步骤：（1）将改性氮化铝粉体、烧结助剂、有机溶剂混合，进行一次球磨，球磨时间为12‑24h，干燥，得到粉体；（2）然后将步骤（1）得到的粉体、改性乙基纤维素、分散剂混合，进行二次球磨，球磨时间为12‑24h，然后进行抽真空脱泡，得到陶瓷浆料；（3）将步骤（2）得到的陶瓷浆料进行流延成型，得到生坯带，然后切片、叠层、排胶、烧结，得到高强度氮化铝陶瓷基板。本申请制备的高强度氮化铝陶瓷基板具有较好的抗弯强度和断裂韧性，有助于陶瓷基板的推广应用。
