Synthesis of W--20%Cu Nanocomposite Powders
W-20%Cu纳米复合粉的制备

W--20%Cu (mass fraction) nanocomposite powders were synthesized by means of combining spray drying and hydrogen reduction process. The composite powders were characterized by using XRD, SEM, TEM. It has been shown that tungsten and copper are homogenously mixed within each particle and the average particle size is about 240 nm, in which the tungsten particles have an average grain size of 16 nm.
