摘要

由于优异的光学和机械性能，Y

-MgO复相纳米陶瓷被认为是红外透明陶瓷的重要候选材料. 尽管如此，在近红外和中红外波段严重的光散射和不必要的吸收方面仍然存在巨大的挑战，这阻碍了该材料在极端恶劣环境中的应用. 在目前的工作中，先通过尿素沉淀法制备了Y

-MgO核壳结构纳米粉体，然后在放电等离子体烧结下制备了Y

-MgO复相纳米陶瓷. 通过热重和差示扫描量热法(TG/DSC)、X射线衍射和扫描电子显微镜分析了核壳结构纳米粉及复相纳米陶瓷. Y

-MgO核壳结构纳米粉体的尺寸约为250 nm，并且制备的陶瓷的平均晶粒尺寸约为360 nm. 透过率在6 μm处为57%，维氏硬度为820 HV. 粉末合成方法为复相纳米陶瓷提供了一种新颖的解决方案，可以轻松调节粒径和不同组分的比例.

Abstract

-MgO composite nano-ceramics are regarded as a significant candidate of infrared transparent ceramics on account of excellent optical and mechanical properties. Nevertheless

a huge challenge remains regarding the critical optical scattering and needless absorption in the near- and mid-infrared bands

which hinders its applications in extreme harsh environments. In present work

-MgO core-shell structure nano-powders were prepared

via

urea precipitation method before that Y

-MgO composite nano-ceramics were prepared under spark plasma sintering. Thermogravimetric and differential scanning calorimetry(TG/DSC)

X-ray diffraction and scanning electron microscope were performed to analyze as prepared core-shell structure nano-powders and composite nano-ceramics. The size of Y

-MgO core-shell structure nano-powders is about 250 nm

and average grain size of the prepared ceramics is approximately 360 nm. The transmittance is 57% at 6 μm

and the Vickers hardness is 820 HV. The powder synthesis method accomplished in present work offers a novel solution for composite nano-ceramics

which easily regulate particle size and proportion of different components.
