i just recently acquired a few pieces of copper impregnated graphite. this stuff is supposed to have high wear resistance in EDM applications So i thought i would give it a shot in a chlorate cell. After a few minutes of operation my electrolyte which is a solution of KCL, turned blueish green. Does any one now what reaction is occuring. i have a few of my own speculations but i thought Id ask if anyone else has experimented with such anodes.
