Copper powder production process

Apr 24, 2020

Jun 09, 2020 The copper powder is electrodeposited from copper sulfate pentahydrate (CuSO4 5H2O) and sulphuric acid (H2SO4) bath. The polarization study is carried out to get an indication of limiting current density or deposition potential. Solutions are prepared with different concentrations of CuSO4 5H2O, i.e., from 0.015 to 0.35 M. Additives like sodium dodecyl

    The process is now widely used for Ti alloy production, but suffers from the fact that the stream’s location is poorly defined and the melt rate rather slow, typically 10–30 kg h –1. This leads to very high (argon) gas consumption per kilogram of powder and also to a relatively coarse distribution (median 40–100 micron), so yields of
