Hey guys, is anyone familiar with a place that will sell platinum electrodes at an affordable price?
I looked at anomet but their contact is down for the day, so I can't inquiry them.

I have heard of platinum wire being used as an electrode, and its relatively affordable.Bot0nist - 26-3-2012 at 06:08
American Pyro Supply (Rolling Thunder) has some really nice ones, but the term affordable is relative to your budget. If you pay for a good one it
will pay for its self in no time at all, trust me. barley81 - 26-3-2012 at 07:35
Elemental scientific sells platinum wire for 7 bucks an inch. I would seal the end of it into some glass tubing for ease of use.

I used 0.5 mm Pt/Ir wire.
Its conductivity was disappointingly below expectations!GreenD - 26-3-2012 at 08:42
Ok -I'll look into all of these. Has anyone ever bought an entire electrochemistry kit? electron source / chamber / electrodes?
Or is there a place that easily explains electrolysis. I understand electrolysis chemically speaking, as redox, but the choices of anodes is beyond
me. I don't know much transition metal chemistry and don't know why, for example, rolling thunder would sell a set of platinum + titanium electrodes,
why wouldn't they sell a set of plat + plat? or tit+ tit?

These seem to be popular and I've used one to create about 1.5lbs. of perchlorate in a 2 liter cell.Berrilium - 12-4-2012 at 10:26
My mother is an audiologist so i got some Platinum wire for free. Unfortunately it is about the size of two hairs.Hexavalent - 12-4-2012 at 10:31
Nice Berrilium!
Apparentley fine platinum gauze it comparatively inexpensive . . .is this a possibility for electrodes? You could even roll a short section into a
cylinder if needed.GreenD - 12-4-2012 at 10:49

awesome didn't see this!
This begs the question, what type of power sources do people use?barley81 - 12-4-2012 at 12:11
I was considering using a computer power supply for small-scale electrolysis (though voltage is set at +3.3, +5, and +12V), and maybe a power supply
from a MOT + rectifier + voltage-smoothing capacitor, but I haven't actually built the supply, nor have I done any electrolysis (school is busy).dann2 - 12-4-2012 at 14:58
have you looked at other electrodes? PbO2 & MnO2, apparently MnO2 makes a good anode during chlorate production (nurdrage youtube, he also has
vids on making them)Geko127 - 25-4-2012 at 15:53
He said he wasent intersted in chloratesrannyfash - 25-4-2012 at 23:28
i know, i just thought they could consider whether the electrochemistry of the electrode might work with their specific reactionhyfalcon - 28-4-2012 at 03:56
If Perchlorates is your interest and you don't want to eat your expensive platinum anode up, you need to start with chlorate production. If you start
with pure chlorate in your cell, you won't have the erosion problems associated with chloride contamination. You also need to run DiChromates to
protect that costly anode.
