I'd give it a go. but how could I get one of these modern MMO anodes?
edit: ok I've done some research starting from the links that pkhow posted. I've come up with place in melbourne that can supply MMO anode mesh made by Lida and Eltech. The guy I spoke to wasn't sure of the exact coating and he thought they were all pretty similar. They mainly sell it for cathodic protection of concrete reinforcing in buildings. I'll get some to try.
pkhow, is there a particular type of coating that you are talking about that could be used to produce perchlorate?
