| 摘 要： | 利用硬脂酸凝胶法制备了SiO2-Y2O3-TiO2复合材料.通过差热-热重分析、X-射线粉末衍射以及傅立叶变换红外光谱等表征手段对所得前驱体及烧结产物的性质进行了研究.结果表明该材料在中、远红外区具有较强吸收,在近红外有很好的反射,可以起到显著的隔热降温效果.

| Abstract: | SiO2-Y2O3-TiO2 hybrid materials were prepared by stearic acid gel method.Thermogravimetry-differential thermal(TG-DTA) analysis,X-ray diffraction(XRD) and FT-IR which were carefully characterized by.The hybrid materials besides a wide and strong absorption during Mid-infrared and Far-infrared areas,and the hybrid materials exhibited an excellent reflectance for Near-infrared.Therefore,which could be used to preserve the energy via the sun from heating the host. |

| Keywords: | stearic acid gel method SiO2-Y2O3-TiO2 hybrid materials mid-infrared absorption near-infrared reflectance |
