Method for preparing yttrium-magnesium multiphase transparent ceramic through non-water-based gel casting
The invention discloses a method for preparing yttrium-magnesium multiphase transparent ceramic through non-water-based gel casting, and belongs to the technical field of ceramic preparation. In order to overcome the problems of water-based system gel casting, the invention provides a method for preparing yttrium-magnesium multiphase transparent ceramic by non-water-based gel casting, which comprises the following steps: ball-milling Y2O3, MgO, a dispersing agent and a non-water-based solvent, then adding epoxy resin and a curing agent, ball-milling again, defoaming, curing and drying the obtained ceramic slurry, thereby obtaining the yttrium-magnesium multiphase transparent ceramic. And carrying out rubber discharging, sintering densification, cooling, hot isostatic pressing sintering, annealing and polishing to obtain the yttrium-magnesium multiphase transparent ceramic. By designing a non-water-based solvent system and selecting a proper gel system, the problems that large-size Y2O3-MgO nano complex-phase infrared transparent ceramic is difficult to prepare, uneven in components and the like are solved, and the yttrium oxide-magnesium oxide nano complex-phase ceramic with complex shape/large size and uniform components can be prepared.
本发明公开了一种非水基注凝成型制备钇镁复相透明陶瓷的方法，属于陶瓷制备技术领域。本发明为克服水基体系凝胶注模成型存在的问题，提供了一种非水基注凝成型制备钇镁复相透明陶瓷的方法，包括：将Y2O3、MgO、分散剂和非水基溶剂进行球磨，然后加入环氧树脂和固化剂再进行球磨，所得陶瓷浆料经除泡、固化和干燥后，再经排胶、烧结致密化、降温、热等静压烧结、退火和抛光，得到钇镁复相透明陶瓷。本发明通过设计非水基溶剂体系，选取合适的凝胶体系，克服了大尺寸Y2O3‑MgO纳米复相红外透明陶瓷制备困难，组分不均等问题，可制得复杂形状/大尺寸、组分均匀的氧化钇‑氧化镁纳米复相陶瓷。
