Aluminum nitride composite board and preparation method thereof
The invention relates to an aluminum nitride composite board and a preparation method thereof.The preparation method comprises the steps that S10, aluminum nitride powder, yttrium oxide powder and a solvent are mixed and then subjected to ball milling, and uniform slurry is obtained; s20, the uniform slurry is subjected to spray granulation, mixed powder is obtained, and the mixed powder is spherical powder; and S30, a graphite plate or a boron nitride plate serves as a gasket, the mixed powder is laid on the gasket, high-temperature hot pressing sintering treatment is conducted, and the aluminum nitride composite plate is obtained. In the aluminum nitride composite board obtained by the method, aluminum nitride is tightly combined with graphite or boron nitride, so that the aluminum nitride composite board has excellent comprehensive performance, is suitable for various high-temperature heat treatment environments and various atmosphere conditions, and has very strong practicability.
本发明涉及一种氮化铝复合板及其制备方法，包括：S10氮化铝粉末、氧化钇粉末和溶剂混合后进行球磨，获得均匀浆料；S20将所述均匀浆料进行喷雾造粒，获得混合粉末，所述混合粉末为球形粉末；S30以石墨板或氮化硼板作为垫片，在所述垫片上铺排所述混合粉末，进行高温热压烧结处理，获得氮化铝复合板。该方法得到的氮化铝复合板中，氮化铝与石墨或氮化硼紧密结合，具有优异的综合性能，适用于多种高温热处理环境，多种气氛条件，有很强的实用性。
