Nano multiphase infrared transparent ceramic material and preparation method thereof
The invention provides a nano multiphase infrared transparent ceramic material and a preparation method thereof. The composition general formula of the material is Y2O3-Mg1-xZnxO, the volume ratio of Y2O3 nano powder to Mg1-xZnxO nano powder is 1: 1, and the molar percentage of ZnO in a Mg1-xZnxO solid solution is 0-30%. According to the Y2O3-Mg1-xZnxO nano multiphase infrared ceramic material disclosed by the invention, scattering is reduced from two aspects, so that the transmittance in a near-infrared band is improved. Firstly, due to doping of ZnO, the refractive index of the MgO phase is increased, the refractive index difference between the MgO phase and the Y2O3 phase is reduced, and secondly, due to doping of ZnO, the densification temperature of the nano multiphase infrared transparent ceramic is reduced, and the grain size is reduced. In addition, due to doping of ZnO, the strength of the composite ceramic is further improved through solid solution toughening, so that the higher performance requirement of the composite ceramic serving as an infrared window material is met.
本发明提出了一种纳米复相红外透明陶瓷材料及其制备方法，该材料的组成通式为Y2O3–Mg1‑xZnxO，其中，Y2O3的纳米粉末和Mg1‑xZnxO的纳米粉末的体积比为1：1，Mg1‑xZnxO固溶体中ZnO的摩尔百分数为0～30％。本发明中的Y2O3–Mg1‑xZnxO纳米复相红外陶瓷材料，从两个方面降低了散射，从而提高了在近红外波段的透过率。首先由于ZnO的掺杂使MgO相的折射率提高，减小了与Y2O3相的折射率差，其次通过ZnO掺杂，降低了纳米复相红外透明陶瓷的致密化温度，减小了晶粒尺寸。此外由于ZnO的掺杂，通过固溶增韧，进一步提升了复相陶瓷的强度，以满足用作红外窗口材料更高的性能要求。
