Transparent ceramic and preparation method thereof
The invention discloses a transparent ceramic which is prepared by the following steps of: weighing and mixing Y2O3 and a doping agent containing Er according to a chemical formula (ErY<1-x>)2O3 (x is more than or equal to 0.0005 and less than or equal to 0.005), and sequentially carrying out ball milling, drying, grinding, sieving and calcining treatment to obtain Er: Y2O3 powder; carrying out molding treatment on the Er: Y2O3 powder to obtain a green body; and placing the green body in a vacuum environment of 1400-1800 DEG C for sintering for 0.5-50 h, then performing hot isostatic pressing sintering in inert gas of 1400-1800 DEG C for 0.5-8 h, finally annealing in air or oxygen atmosphere of 600-1300 DEG C for 0.5-30 h, and performing two-side polishing to obtain Er: Y2O3 transparent ceramic. The Er: Y2O3 transparent ceramic with high optical quality can be prepared by adopting a mode of combining vacuum sintering and hot isostatic pressing treatment on the premise of not additionally adding a sintering aid. Under excitation of a proper pumping source, <4>I<13/2>-><4>I<15/2> energy level transition of Er < 3 + > ions can be utilized, and under the condition that a pump light darkening effect is not generated, 1.6 [mu] m laser which can be safely absorbed by human eyes can be output.
本发明公开了一种透明陶瓷，包括将Y2O3和含Er的掺杂剂按化学式(ErxY1‑x)2O3进行称重混合，其中，0.0005≤x≤0.005，并依次经过球磨、烘干、研碎、过筛和煅烧处理，得到Er:Y2O3粉体；将Er:Y2O3粉体进行成型处理，得到素胚；将素坯放置于1400‑1800℃的真空环境中烧结0.5‑50 h，可再于1400‑1800℃的惰性气体中热等静压烧结0.5‑8 h，最后在600‑1300℃的空气或氧气气氛下退火0.5‑30 h，经两面抛光后，得到Er:Y2O3透明陶瓷；本发明采用真空烧结与热等静压处理结合的方式，可以在不额外添加烧结助剂的前提下，制备出高光学质量的Er:Y2O3透明陶瓷，在合适的泵浦源的激发下，可利用Er3+离子的4I13/2→4I15/2能级跃迁，在不产生泵浦光暗化效应情况下，可以实现能够被人眼安全吸收的1.6μm激光输出。
