Laser-damage-resistant transparent ceramic and preparation method thereof
The invention discloses a laser-damage-resistant transparent ceramic and a preparation method thereof, and the preparation method comprises the following specific steps: powder mixing: adding lutetium aluminum garnet ceramic powder, commercial phase reinforced particle absolute ethyl alcohol and high-purity alumina balls into a nylon ball milling tank, and carrying out ball milling by using a planetary ball mill to obtain slurry; drying and sieving: after the powder is fully and uniformly mixed, putting the ball-milled slurry into a drying oven for drying, and sieving with a 100-200-mesh nylon sieve to obtain uniform powder; calcining: calcining the powder in a crucible to remove organic impurities introduced in the ball milling process; dry-pressing molding: carrying out dry-pressing molding on the calcined powder under the pressure to obtain a biscuit, and carrying out cold isostatic pressing to further improve the density of the biscuit; performing hot isostatic pressing, namely presintering the prepared biscuit in an air atmosphere, and performing hot isostatic pressing treatment in an argon atmosphere to eliminate residual pores; and double-side polishing: polishing the double sides of the obtained biscuit to 3-6mm to obtain the lutetium aluminum garnet transparent ceramic with the high laser damage threshold.
本发明公开了一种抗激光损伤的透明陶瓷及其制备方法，其制备方法具体步骤为粉体混合：将镥铝石榴石陶瓷粉体、商用相增强颗粒无水乙醇和高纯氧化铝球加入尼龙球磨罐中，使用行星球磨机球磨得到浆料；烘干过筛：粉体充分混合均匀后，将球磨完的浆料放置于烘箱中烘干，再过100‑200目尼龙筛得到均匀的粉末；煅烧：将粉末置于坩锅中煅烧除去球磨过程引入的有机杂质；干压成型：将煅烧后的粉末在的压力下干压成型得到素坯，并冷等静压进一步提高素坯密度；热等静压：制备的素坯在空气气氛中预烧后，再在氩气气氛中热等静压处理以消除残余气孔；双面抛光：将得到的素坯双面抛光至3‑6mm，得到高激光损伤阈值的镥铝石榴石透明陶瓷。
