Preparation and Properties of Al/Bi2O3 Composite Particles with Medium-low Infrared Emissivity for Infrared Camouflage
摘要
Abstract
Better coated Al/Bi2O3 composite particles were prepared using bismuth nitrate and flaky aluminum powders as raw materials by co-precipitation method though the recombination of Bi2O3 on the surface of flaky aluminum powders. In order to obtain a better IR camouflage performance, the morphologies, phase composition were characterized by SEM, XRD and IR. The infrared emissivity of Al/Bi2O, composite particles was tested by infrared emissivity instrument. The results showed that the infrared emissivity of composite particles with yellow body color sintered under temperature 450℃. was 0.73. The precursors were produced under precipitating temperature 50 ℃ for 2 h. The sheet aluminum powders were coated by Bi2O3, then their color became yellow. They could avoid the "betray oneself" , oxidation and provide an excellent material for infrared stealth camouflage.关键词
