High-strength low-radiation light-transmitting window material and preparation method thereof
The invention provides a high-strength low-radiation light-transmitting window material and a preparation method. Slurry which contains Y2O3, ZrO2 and SrO and is prepared through ball milling is stirred at a high speed in a magnetic stirring mode, the doping uniformity is improved, the mechanical strength of the Y2O3 window material is improved by doping ZrO2 and Y2O3 solid solution, meanwhile, valence state balance is achieved by doping SrO with the molar ratio equal to that of ZrO2, thus the densification degree and densification rate of the sintered Y2O3 window material are improved, and the sintering time is also shortened. The Y2O3-ZrO2-SrO system solid solution phase window material prepared by adopting the method has the characteristics of high bending strength, high temperature and low radiation, and also has relatively high transmittance in visible-medium wave infrared bands, so that the application range of the Y2O3 window material is widened, and the application range of the Y2O3-ZrO2-SrO system solid solution phase window material is expanded. The window material can be widely applied to the fields of infrared high-temperature imaging windows, optical windows/fairings used in high-speed flight environments and the like.
本申请提供一种高强度低辐射透光窗口材料及制备方法，采用磁力搅拌的方式对含Y2O3、ZrO2、SrO的球磨制备的浆料进行高速搅拌，提高了掺杂的均匀性，通过掺入ZrO2与Y2O3固溶提高了Y2O3窗口材料的力学强度，同时通过掺入与ZrO2等摩尔比例的SrO来实现价态平衡，提高了Y2O3窗口材料烧结后的致密化程度和致密化速率，也缩短烧结时间。采用该方法制备出来的Y2O3‑ZrO2‑SrO体系固溶相窗口材料具有高弯曲强度、自身高温低辐射的特点，而且在可见‑中波红外波段也具有较高的透过率，拓宽了Y2O3窗口材料的应用范围，可适广泛用于红外高温成像窗口及高速飞行环境下使用的光学窗口/整流罩等领域。
