摘要: Y2O3透明陶瓷具有优良的光学和物理化学性能,在固体激光器、透明窗口等领域有广阔的应用前景。粉体分散性一直是研究者在透明陶瓷制备过程中关注的重要方面,本文以国产商业纳米Y2O3粉体为原料,通过机械分散结合HF酸洗的方式提高粉体分散性,湿法成型后真空烧结,制备具有较高光学性能的Y2O3透明陶瓷。结果表明,超声结合酸洗的方式可有效提升粉体分散性和烧结活性,粉体D50从3.5 μm降低至1.4 μm,制备得到Y2O3透明陶瓷的光学性能有明显提升,400 nm处透过率从酸洗前的65.5%提升至酸洗后的71.5%,为Y2O3透明陶瓷在固体激光器和窗口领域的应用提供可靠的制备工艺及理论基础。

Abstract: Y2O3 transparent ceramics have broad applications including solid-state lasers, transparent windows, etc., owing to its excellent optical and physical-chemical properties. The dispersity of the powder among the fabrication process of transparent ceramics has attracted much attention from researchers for decades. In this paper, domestic commercial nanopowder was adopted as the starting material, and the dispersion of the powder was improved through mechanical force combined with HF acid-washing. Y2O3 transparent ceramics with high transmittance were achieved by slip casting and vacuum sintering. The results show that ultrasonic combined with HF acid-washing is an effective way to improve the dispersibility and sinterability of the powder, the D50 of the powder reduces from 3.5 μm to 1.4 μm. The transmittance of the Y2O3 ceramic at 400 nm is improved from 65.5% to 71.5% for the sample after ultrasonic combined with HF acid-washing process. The results lay a solid foundation of preparation technology and theoretical basis for the application of Y2O3 transparent ceramics on solid-state lasers and transparent window materials.
