Aluminum nitride ceramic and preparation method thereof
The invention discloses aluminum nitride ceramic and a preparation method thereof, and relates to the technical field of ceramic preparation. The preparation method of the aluminum nitride ceramic comprises the following steps: S1, carrying out ball milling on aluminum nitride powder, a modifier and absolute ethyl alcohol, washing with absolute ethyl alcohol, and drying to obtain modified AIN; s2, mixing a cross-linking agent component with deionized water, continuously adding a dispersing agent, the modified aluminum nitride powder and tetramethylammonium hydroxide, carrying out ball milling, and adjusting the pH value of the slurry to obtain the slurry; and S3, mixing the slurry and an initiator, and performing vacuum defoaming, pouring, curing molding, demolding, drying, glue discharging and sintering to obtain the aluminum nitride ceramic. The modified aluminum nitride prepared by the invention has excellent hydrolysis resistance, and aluminum nitride ceramic prepared from the modified aluminum nitride powder has excellent mechanical properties.
本发明公开了一种氮化铝陶瓷及其制备方法，涉及陶瓷制备技术领域。本发明氮化铝陶瓷的制备方法，包括如下步骤：S1：氮化铝粉末、改性剂和无水乙醇球磨、无水乙醇洗涤、干燥，得到改性AIN；S2：将交联剂组分、去离子水混合，继续加入分散剂和改性氮化铝粉末、四甲基氢氧化铵，球磨、调节浆料pH值，得到浆料；S3：将浆料、引发剂混合后真空脱泡、浇注、固化成型、脱模、干燥、排胶、烧结，得到氮化铝陶瓷。本申请制备的改性氮化铝抗水解性能优良，利用该改性氮化铝粉末制备的氮化铝陶瓷具有优良的力学性能。
