英文摘要Y2O3-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, Y2O3-MgO core-shell structure nano-powders were prepared via urea precipitation method before that Y2O3-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 Y2O3-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 渭m, 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. 漏 2021, Science Press.
