热处理温度对Bi_2O_3/ATO复合功能填料红外-可见光兼容隐身性能的影响

Effects of heat treatment temperature on infrared and visible light stealth properties of Bi_2O_3/ATO mixed burning filler

采用固相法制备了Bi2O3/ATO复合功能填料,借助于XRD、SEM、分光光度计和辐射率仪研究了热处理温度分别对复合功能填料的物相组成、微观形貌、可见光及红外隐身性能的影响。结果表明,随着热处理温度的升高,复合功能填料的红外辐射率先下降后升高,当热处理温度为800℃时,复合功能填料的红外辐射率最低,达到了0.67。填料的最高反射峰出现在黄橙光范围内,但是,样品在可见光区的反射峰面积和平均反射率均随着热处理温度的升高逐渐增大。因此,复合功能填料的颜色亮度可以根据煅烧温度进行调节,适于制备多色红外迷彩涂料。

Bi203/ATO powders were prepared by solid state reaction. The effects of heat treatment temperature on phase composition, morphology, visible light and infrared stealth properties were studied by XRD, SEM spectrophotometer, ultraviolet-visible spectrophotometer and infrared emissivity analyzer, respectively. The results showed that the infrared emissivity of the Bi2 03/ATO powders decreased first and then increased with the increasing of heat treatment temperature. The minimum infrared emissivity reached 0.67 when the heat treatment temperature was 800°C. The reflection peak appeared in the range of yellow optical wavelength and orange optical wavelength. However, both the area and the average of the reflection in the whole visible wavelength increased with the increasing of heat treatment temperature. Therefore, the colors could be adjusted by controlling the heat treatment temperature. Bi20a/ATO powders were suitable for preparing the multicolored infrared camouflage packing.
