Paper Abstract

A sol-gel method was successfully used to synthesize Y2O3-MgO composite powder with a grain size below 30nm. Results from X-ray diffraction revealed how the microstructure evolved with increasing heat treating temperature. Taking advantage of high heating rate, spark plasma sintering (SPS) technique was used to sinter the nanopowder, resulting in a fully dense nanocomposite with grain size below 100nm. The transmittance can be enhanced by optimizing sintering parameters as well as appropriate post-sinter annealing. The fully consolidated nanocomposite exhibits an optical transmittance between 75% and 84% over infrared wavelength range between 3μm and 6μm. This kind of nanocomposite has a great potential to be used as infrared transparent material.
