Electrolytic Manganese Metal Flake 99.7%

Electrolytic metal manganese refers to the elemental metal by using an electrolytic cell to electrolyse manganese salt precipitated by acid leaching of manganese ore. It is firm and brittle flakes with irregular shape. It is bright on one side with silver white color but rough on the other with brown color. The purity of electrolytic manganese is very high, containing 99.7% manganese.
