Aluminum oxide ceramic sintering method and obtained aluminum oxide ceramic
The invention discloses an alumina ceramic sintering method and alumina ceramic obtained by the same, and belongs to the field of ceramic preparation. Comprising the following steps: S1, ball-milling and mixing aluminum oxide powder, an aluminum oxide precursor and an adhesive to obtain slurry, and then drying, crushing and sieving to obtain ceramic powder; s2, carrying out dry pressing molding on the ceramic powder to obtain a ceramic green body; s3, sintering the ceramic green body to obtain an aluminum oxide ceramic finished product; the component of the aluminum oxide precursor comprises aluminum isopropoxide. By adding the aluminum oxide precursor as the sintering aid, the sintering temperature of the aluminum oxide ceramic is effectively reduced, the problems of high brittleness and the like of the aluminum oxide ceramic are solved, and the toughness of the aluminum oxide ceramic is improved, so that the consistency of the density and the hardness of the product is optimal, generation of heterogeneous phase materials is avoided, the process is simple and convenient, and the production cost can be effectively reduced. The method is suitable for industrial production.
本发明公开了一种氧化铝陶瓷烧结方法及其得到的氧化铝陶瓷，属于陶瓷制备领域。包括：S1、将氧化铝粉体、氧化铝前驱体和粘合剂球磨混合得到浆料，然后干燥、粉碎、过筛，得到陶瓷粉体；S2、将所述陶瓷粉体通过干压成型得到陶瓷坯体；S3、将所述陶瓷坯体通过烧结得到氧化铝陶瓷成品；所述氧化铝前驱体的成分包括异丙醇铝。本发明通过添加氧化铝前驱体作为烧结助剂，有效降低氧化铝陶瓷的烧结温度，同时解决氧化铝陶瓷脆性大等问题，提高氧化铝陶瓷韧性，从而使产品密度和硬度一致性达到最优，且避免异质相材料的生成，工艺简便，可以有效降低生产成本，适用于工业化生产。
