摘　　要：对以SiO_2、Al_2O_3、MgCO_3、CaCO_3和稀土氧化物等为原料制备的超细陶瓷粉体进行了红外干扰性能研究。研究结果表明,不同粒径的陶瓷粉体对红外辐射的干扰效果和持续时间有很大差异,最终确定超细陶瓷粉体的最佳平均粒径应处在3.5～5.5μm范围。In this paper, the infrared jamming performance of ultrafine ceramic powders which were prepared from SiO2, Al2O3, MgCO3, CaCO3 and rare-earth oxides has been studied. The results revealed that the infrared jamming effect and jamming duration were very different when the particle size varied, and optimal average particle size of ultra fine ceramic powders should be ranged from 3.5μm to 5.5μm.
