distribution of Cu nanopowders Fig.4 shows the typical X-ray diffraction(XRD) pattern for the specimen. The relatively broad XRD peaks indicate the nano-crystalline nature of the particles. Five broad peaks... single crystalline primary particle. The BET method based on low-temperature adsorption of nitrogen can be used to determine the specific surface area of the powder. If the powder consists of solid......
