摘      要：The particle sizes of ultrafine powders are between cluster and fine powders, with theparticle diameters generally in the range of 1--100nm. When compared with commonmaterials consisting of bigger particles, materials consisting of nanometer-size particleshave many special properties. These include small-sized effect, surface and interface
