A place to buy platinum plated titanium anodes ?
I would like someone to indicate me a place that sells platinum plated titanium anodes to individuals, and ships worldwide. I want the small ones, maybe 5 to 15 square inches.
Check out these rod anodes . . .
They're a London based company!
Here's where I bought my first one:

Good. But it is listed as an anode for jewelry plating, will it work in a perchlorate cell? Also, do you know what is the maximum current density this anode can take?
I was pushing 10-15 amps with a car battery charger through it with no problem. Yes, it will make perchlorate. I abused my anode by going all the way from Chloride to Perchlorate with it, so it does work.
Pardon "zombying" the thread but since you posted this how have the electrodes held up to chloride to perchlorate cell runs? Having a heck of a time finding a starting point on this kind of thing. Dann2's site is a no show for some time now, so I can't ask him. Quote: Originally posted by hyfalcon I was pushing 10-15 amps with a car battery charger through it with no problem.

anybody seeing profit in me buying 5 of those 50 x 50 mm??
I could potentially drag the price down to 70 euros each 50 x 50 mesh if anybody would be interested without having too much of a profit myself.. (:
im located in EU, if anybody would be interested in 70 euros for a 50 x 50 mesh platinized titanium I could order a decent amount to get a discount, PM me..

Interesting pricing?
Using them as cathode and anode (and periodically reversing polarity) can significantly prolong their working life . . .
entirely sure about that?? very interesting idea..
it could be done simply by shifting - and + per each run making a decently equal reverse

Yes, Pt lost from the anode will plate the cathode fairly uniformly so that only the very minimum Pt is lost in the solution..
That's the theory, anyhoo . . . ?

I have since switched off to MMO mesh for my chlorate production. Only when I have purified chlorate do I switch it to my platinum anodes. Wish I had a scrap platinum crucible to cut up.

In my experience, what it will do is de-laminate from the titanium substrate leaving particles in the bottom of your reaction vessel.
Why do you specify titanium base? The highest quality platinum clad electrodes use niobium as a base for better bonding with the platinum.

Anomet is a good place to get anodes.
Delamination occurs when a plated Ti anode becomes exposed to the action of the electrolyte ' the oxide layer which forms displaces the Pt layer at the anode surface!
I bought my first Pt clad Ti anode from a wholesale jewelry-making equipment supplier in Australia; they no longer sell them however.
After a quick check of the web, this place came up!
http://www.jewelerstoystore.com/Platinum_Clad_Anode_p/p60-5....
They have a 6" x 1" for $109 and a 4" x 1" for $80.
Only use the anode in pure chlorate solution to make perchlorate if you desire it to last.
Since I can't edit my other post: I didn't mean to start the anode wars again. I asked as MMO is a pain in the butt to find (thank god sbbspartan runs a site with mmo mesh in stock) and I was giving thought to a straight chloride to perchlorate cell but I didn't know how bad the platinum erosion was doing that assuming the Pt on Ti mesh for the anode and a titanium cathode. Yes, I know look in Technochemistry for more but still: didn't mean to start the war again.
He doesn't have any now, but ALL my MMO that I have I bought is from laserred on ebay. I've got quite a bit, pm me if you need some.

Could one coat own electrodes with platinum? This would save great amounts of money; by my calculations, the cost of readily sold electrodes is 10-50 fold the actual cost of Ti+Pt metal required, thus rendering them effectively unobtainable for amateurs. I'd believe it should be first turned into chloroplatinic acid and then maybe ammonium platinate and electrolyzed as common coating baths. Anyone got experience playing with this?
Can't get low-stress coatings from acid Pt(IV) baths.

Interesting, I bought this same anode and was not able to get any perchlorate production even after two weeks of run time on 3 liters of solution at 5.1V ... made chlorate by the ton though.
What were your conditions in your reaction vessel? Needs 70C or so.
70C really? Never saw that in literature I read, but I was running between 45-50 C with pH about 8 in a sodium-based solution. The anode just has what appears to be powdered platinum sintered onto the surface of the Ti base. Very corrosion-proof but never got a positive on the methylene blue test.
I always use potassium salt. No problem seeing where you are with it.
