超细粉末无论在传统的结构和功能材料,还是在现代的高技术材料领域都得到了广泛应用。尤其是异形超细粉体材料,它一出现就吸引广大材料科学家的兴趣,已经初步显现出了一些不同其他常规材料的新奇的特性,在许多特殊领域正发挥着重大作用。异形超细粉体(ultra-fine special-shapde powders)是指具有特殊形状的、粒度为100纳米左右的超细颗粒。它具有两个最主要的特 Ultrafine powder has been widely used in both traditional structural and functional materials and in modern high-tech materials. Especially the special-shaped ultrafine powder material, which appeals to the vast majority of material scientists as it emerges, has initially shown some novel characteristics of various other conventional materials and is playing a major role in many special fields. Ultra-fine special-shapde powders are ultrafine particles with a specific shape and a particle size of about 100 nanometers. It has two of the most important specialties
