摘　　要：多孔钨由于其具有高熔点、低密度、低热膨胀系数和高强度的特点,在航空航天、电力电子及冶金工业等领域有广泛的应用,近年来受到国内外学者们的研究。本文介绍了多孔钨目前已有的几种制备方法、制备原理以及各自的性能,最后对这几种方法的优缺点进行了比较。Because of the high melting point, low density, low thermal expansion coefficient and high strength char- acteristics of porous tungsten, there was a wide range of applications in the field of aerospace, power electronics and met- allurgical industry, and there were some scholars at home and abroad study on it in recent years. Several existing prepara- tion methods, preparation principle and the respective properties of porous tungsten were described, and these methods were compared.
