The production of very fine copper powder | SpringerLink
Two methods of preparing copper powder were developed: one employing the gradual addition (drop by drop) of a saturated CuSO4 solution to a Ti2(SO4)3 solution (periodic method) and another employing the anodic dissolution of metallic copper in a Ti2(SO4)3 solution (continuous method). In both cases, the process is.
