摘　　要：研究3种W型六角晶系锶铁氧体(BMA-PX,WPS,WPX)作吸波填料对甲基乙烯基硅橡胶(MVQ)吸波性能的影响。结果表明:3种W型六角晶系锶铁氧体均为无规的碎石状颗粒,元素组成不同,吸波性能差异较大。铁元素质量分数较大的BMA-PX吸波MVQ磁损耗较大,容易实现阻抗匹配,在中高频下的电磁波反射率低,吸波性能优异。In this work,three kinds of W-type hexagonal strontium ferrite（BMA-PX,WPS,WPX） were studied as absorbing filler in MVQ. All three ferrite fillers had irregular shape,and the element compositions and absorbing properties were different. It was found that the MVQ with BMA-PX which had higher iron content possessed high magnetic loss;it was easy to achieve impedance matching and showed low electromagnetic waves reflectivity in high frequencies and superior absorbing properties.
