Hmm,
I read somewhere that over time Br2 attacks glass over long time exposure, maybe it was at higher temperatures. now that I think about it it is most likely NaBr as that sample was from the small amount I salvaged from the accident.




all above information is intellectual property of Pyro. :D

@Cheddite Cheese: Didn't you have any pitting corrosion of the titanium parts of your anode? I also tried to use my MMO anode for making KBrO3, but this resulted in formation of flocculent stuff from the uncovered titanium mesh of my MMO anode, so I quit the electrolysis. I did not want to destroy/erode the anode.


None of the non-coated portion of my anode was below the surface of the liquid in the cell, so I had no trouble with it. It's plausible that it could damage exposed Ti, but I'm not inclined to find out.




As below, so above.

I can verify bromide attacks 6Al-4V titanium alloy as anode.
