Abstract
Bi 2O 3/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 Bi 2O 3/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. Bi 2O 3/ATO powders were suitable for preparing the multi-colored infrared camouflage packing.
