The invention discloses a preparation method of an aluminum oxide ceramic special-shaped part, and belongs to the technical field of ceramic preparation. The method comprises the following steps: mixing alpha-Al2O3, Al2O3, an auxiliary raw material, a photoinitiator and zirconia beads, carrying out ball milling to obtain slurry, pouring the slurry into a mold, irradiating ultraviolet light, molding, sintering, cooling, and carrying out surface treatment to obtain the aluminum oxide ceramic special-shaped part. According to the invention, the components and proportion of the slurry are optimized, so that the slurry can be suitable for an ultraviolet irradiation environment, a ceramic green body is easier to form, time is saved, the slurry can be suitable for preparing a complex special-shaped ceramic part, the method is simple and convenient, deformation of the green body in the forming process is effectively reduced, and subsequent treatment is facilitated.
本发明公开一种氧化铝陶瓷异形件的制备方法，属于陶瓷制备技术领域。该方法先将α‑Al2O3、Al2O3、辅助原料、光引发剂和氧化锆珠混合，球磨成浆，然后把浆体灌入模具中，照射紫外光成型，烧结，冷却后进行表面处理，获得氧化铝陶瓷异形件。本发明优化浆料组分和配比，使浆料可适用紫外光照射环境，使陶瓷坯体更易成型，节省时间，且可适用于制备复杂的陶瓷异形件，方法简单方便，有效减少成型过程中坯体的形变，有利于后续的处理。
