Aluminum nitride whisker reinforced aluminum nitride ceramic material for electronic parts
The invention relates to the field of chemical ceramics, and particularly discloses an aluminum nitride whisker reinforced aluminum nitride ceramic material for electronic parts, which comprises silicon nitride, aluminum powder, absolute ethyl alcohol, compact silicon carbide balls, a dispersing agent and a grinding medium matched ball milling container, 10-15 wt% of aluminum powder, 6-9 wt% of absolute ethyl alcohol, 60-90 wt% of compact silicon carbide balls and 1 wt% of a dispersing agent are placed in a ball milling device, grinding is carried out for four times, the grinding time is 20 minutes each time, the grinding time is 10 minutes intermittently, and high temperature in the grinding process is effectively prevented; according to the aluminum nitride whisker reinforced aluminum nitride ceramic material for the electronic parts, the preparation process of beta-Si3N4 is optimized, so that the output result of the whole subsequent preparation is more stable, that is, the high unification and high quality of the prepared material are ensured, and the raw materials are subjected to secondary grinding in cooperation with fused quartz powder and microcrystalline glass; and overlarge crystals in the high-temperature plasticity process are avoided, and the compressive strength of the prepared material is effectively improved.
本发明涉及化工陶瓷领域，具体公开了电子零件用氮化铝晶须增强氮化铝陶瓷材料，包括氮化硅、铝粉、无水乙醇、致密碳化硅球、分散剂和研磨介质配合球磨容器，具体制备步骤如下：101、球磨：首先将铝粉10‑15wt％、无水乙醇6‑9wt％、致密碳化硅球60‑90wt％、分散剂1wt％放置于球磨设置中，研磨四次，每次研磨时间为二十分钟，间歇时常为十分钟，有效防止研磨过程中的高温。该电子零件用氮化铝晶须增强氮化铝陶瓷材料，对β‑Si3N4制备过程的优化处理，使得整个后续制备输出的结果更为稳定，即本发明保证了制备材料的高统一化和高质量化配合融石英粉和微晶玻璃对原材料进行二次研磨，避免了高温塑性过程的晶体过大，有效的提高了制备后材料的抗压轻度。
