Can anyone suggest or provide about chemical etching or electrolytic polishing method or relevant information for pure copper.
For chemical etching
Klemm solution or
The mixture :
100-120 ml of water ou ethanol
20-50 ml of HCl
5-10 g of Ferric chloride (Fe III)
tks, Atli
For electrolytic polishing of pure copper:
80 ml H3PO4 + 20 ml H20 (2 distilled water)
U~12 V, J~0.4-1 A
Tks, Khisamov. Another question is what degree of temperature is carried out for this electrolytic polishing. thank you for ur reply in advance.
at room temperature
