Can anyone help me out - what is an effective acid to etch graphite? if any, what acid would be useful for etching graphite??? thanks.....................

Sorry I dont have the answer was just gona say Hi and welcome to the forums
I can tell you that water is probably not the best acid to use tho if that helps.

I'm not a chemist, but if I recall correctly, graphite is very resistant to acid.
I'd sand-blast it, myself.

Simple battery acid would do the trick.

No chance with an acid.
At macroscopic scale, use mechanical methods. A chance with a blowtorch also, injecting much oxygen.
Graphite is often put in form by grinding.
How big is your part, how deep do you want to etch, shall it be precise or good looking or have a complicated form...?

Hello hungz, et al.
At high temperatures there are elements that will form carbonates with graphite. Silicone is one of these elements. This approach may be applicable to your endeavor.

Stick to what I already said and see the results.

And see nothing happens.
Graphite is chosen as a battery electrode because it resists chemicals.
