Zusammenfassung:	PURPOSE:To produce fine copper powder in large quantities at a low cost by carrying out electrolysis in an electrolytic bath obtd. by adding Ti to a copper sulfate bath acidified with sulfuric acid to a specified concn. to electrodeposit copper on the cathode in the form of fine powder. CONSTITUTION:Ti is added to a copper sulfate bath acidified with sulfuric acid to 0.1-5g/l concn. to obtain an electrolytic bath and electrolysis is carried out in the electrolytic bath to electrodeposit copper on the cathode in the form of fine powder. In this case, copper is used as the cathode and anode. Fine copper powder can be produced in large quantities at a low cost.
