The invention discloses aluminum nitride-based dielectric ceramic and a preparation method thereof. According to the design formula of the aluminum nitride-based dielectric ceramic, metal powder is weighed and mixed according to a certain proportion, and metal powder M for doping is obtained; aluminum nitride powder, a sintering aid, metal powder M for doping, a dispersing agent and a solvent are put into a ball mill according to a certain proportion and mixed and ground under a certain technological condition, and mixed slurry is obtained; performing drying treatment on the mixed slurry, removing redundant solvent, and performing crushing treatment to obtain mixed powder; carrying out compression molding treatment on the mixed powder to obtain a biscuit with a certain shape and size; the biscuit is placed in a glue discharging furnace to be subjected to glue discharging treatment, organic matter in the biscuit is removed, and therefore the ceramic biscuit without residual carbon is obtained; placing the ceramic biscuit subjected to glue removal in a high-temperature sintering furnace, and performing high-temperature sintering in a nitrogen atmosphere to obtain the co-crystallized aluminum nitride-based dielectric ceramic material. And the ceramic material is subjected to shape processing and surface treatment.
本发明公开了一种氮化铝基电介质陶瓷及其制备方法。根据氮化铝基电介质陶瓷的设计配方，将金属粉体按一定比例进行称重混合，得到掺杂用金属粉料M；将氮化铝粉体、助烧剂、掺杂用金属粉料M、分散剂、溶剂按一定比例放入球磨机中，在一定工艺条件下进行混合研磨，得到混合浆料；将混合浆料进行干燥处理，除去多余溶剂，经过破碎处理，得到混合粉料；将混合粉料进行压制成型处理，得到呈一定形状和尺寸的素坯；将素坯置于排胶炉中进行排胶处理，以排除素坯中的有机物，从而获得不含残余碳的陶瓷素坯；将排胶后的陶瓷素坯置于高温烧结炉中，在氮气气氛下进行高温烧制，得到共晶化的氮化铝基电介质陶瓷材料；将陶瓷材料进行形状加工并进行表面处理。
