Preparation method of high-transmittance Ce: YAG transparent ceramic
The invention discloses a high-transmittance Ce: YAG transparent ceramic preparation method, which comprises: adding tetraethoxysilane and Al2O3 as raw materials into an ethanol solution, uniformly stirring at room temperature, heating to obtain a core-shell structure precursor, washing and drying to obtain a core-shell structure oxide Al2O3 (at) Si; al2O3, Y2O3 and CeO2 are used as raw material powder, raw materials are weighed according to the stoichiometric ratio of corresponding elements in the chemical formula (Y1-xCex) 3Al5O12, a sintering aid, absolute ethyl alcohol, a dispersing agent, the core-shell structure oxide and the raw material powder are put into a ball milling tank together to be ground, and mixed slurry is obtained; the mixed slurry is sequentially subjected to drying, sieving, calcining, dry pressing forming, plastic packaging, sintering, annealing and polishing, and then the transparent ceramic is obtained. According to the method, grain boundary pores can be filled, particle rearrangement can be accelerated, and the sintering activity of the ceramic powder is improved, so that the density of the ceramic is improved, and the transmittance of the ceramic is improved.
本发明公开了一种高透过率Ce:YAG透明陶瓷的制备方法，该方法包括：以正硅酸乙酯和Al2O3作为原料，加入至乙醇溶液中，室温下搅拌均匀后加热得到核壳结构前驱体，洗涤干燥后得到核壳结构氧化物Al2O3@Si；以Al2O3、Y2O3和CeO2作为原料粉体，按化学式(Y1‑xCex)3Al5O12中对应元素的化学计量比称取各原料，将烧结助剂、无水乙醇、分散剂、核壳结构氧化物与原料粉体一起放入球磨罐研磨得到混合浆料；将混合浆料依次经过干燥、过筛、煅烧、干压成型、塑封、烧结、退火、抛光后得到所述透明陶瓷。该方法可填充晶界气孔和加快颗粒重排，提高陶瓷粉体的烧结活性，从而提高陶瓷的致密度，进而提升陶瓷的透过率。
