Production process of high-performance microcrystalline alumina composite ceramic
The invention relates to the field of composite ceramics, and discloses a high-performance microcrystalline alumina composite ceramic production process, which comprises the following steps: selecting high-purity alumina powder and composite material powder, and mixing; carrying out ball milling treatment on the mixed powder to obtain uniform particle distribution and fine particle size, and carrying out drying treatment; mixing the dried powder with an organic binder and a solvent to prepare slurry, and injecting the slurry into a mold to obtain a required shape; demolding the molded ceramic body, and carrying out primary sintering; grinding and finishing the primarily sintered ceramic green body to remove roughness and impurities on the surface so as to obtain a flat surface; carrying out secondary sintering on the ground and trimmed ceramic green body; carrying out coating treatment on the surface of the ceramic subjected to secondary sintering; the produced ceramic is subjected to performance detection, and qualified products are packaged and stored.
本发明涉及复合陶瓷领域，且公开了高性能微晶氧化铝复合陶瓷生产工艺，选择高纯度的氧化铝粉末和复合材料的粉末，并进行混合；将混合后的粉末进行球磨处理，以获得均匀的颗粒分布和细小的颗粒尺寸，并且进行干燥处理；将干燥后的粉末与有机粘结剂和溶剂混合，制备成浆料，然后将浆料注入模具中，得到所需要的形状；成型后的陶瓷坯体进行脱模，并进行初次烧结；对初次烧结后的陶瓷坯体进行研磨修整，以去除表面的粗糙度和杂质，得到平整的表面；将经过研磨修整的陶瓷坯体进行二次烧结；在二次烧结后的陶瓷表面进行涂层处理；对生产出的陶瓷进行性能检测，合格的产品进行包装和存储。
