Research on Preparation of W-Cu Nano Composition Powder by Precipitation Method
Abstract:
W-Cu precursor was prepared by chemical precipitation. Then the superfine W-Cu composite powder was prepared by roasting and hydrogen reduction process. The composite powder sample were characterized by SEM and XRD. The experimental results show that component uniform and stabilising ratio W-Cu precursor can be prepared by controlling pH of solution, then W-20%Cu uhrafine composite powder was prepared by hydrogen reduction proces ,The sizes of three compositions in the powder(Cu0.4W0.6, W and Cu)was to nanometer, in which the size of Cu0.4W0.6 and W was 40nm while the size of Cu was 70nm.
