Abstract
Bi2O3/ATO powders were prepared by solid state reaction. The phase composition, reflectivity in visible region, morphology, elemental composition, infrared transmittance and infrared emissivity of the obtained Bi2O3/ATO powders were characterized by XRD, ultraviolet-visible spectrophotometer, SEM, EDS, FT-IR and infrared emissivity analyzer, respectively. The results showed that the obtained Bi2O3/ATO powders possessed excellent infrared transparency. Moreover, infrared emissivity decreased first and then increased with the increase of the Bi2O3 contents, and infrared emissivity reached the minimum 0.67 when the content of Bi2O3 was 70wt%. In addition, the colors could be adjusted by changing the content of Bi2O3. Bi2O3/ATO powders were suitable for preparing the multicoloured infrared camouflage packing.
