Hey,
Since chlorate is hard too obtain where I live I decided to try and built a cell for electrolytic preparation of sodium chlorate out of a sodium chloride solution.
I did some research on this subject and so I was wandering or any of you guys has experience with such cells and if so, how did you build it?

I have tried a few times but every time the electrodes have corroded off and i have been left with a chunky multi-coloured soup.

What type of electrodes did you guys use?
Carbon & Steel isn't the best choice. It's really worth to look for platinum sheets(?) or electrodes. The electrolysis is fairly easy with Pt electrodes. For chlorates & perchlorates anode & kathode = Pt - Cu is possible as kathode but Pt is better.
They should be the same size, for example 10cm2 (20cm2 surface). For chlorates set a current of ~0,2A per cm2 and 10-14V. Temp should be at 50-60 C. Also add a tiny amount potassiumdichromate to prevent the hydrogen that is formed at the kathode from lowering the yield.
For 100ml H20 take 20g KCl, 0,2g K2CrO4. Dissolve and run the cell for 50 amperehours(?) (current=10A time 5h, current=1A time 50h)
I had very good results with a 400ml Cell.

Do a search for Mike Browns KCLO3 Production. Can't remember the URL off hand, but this is probably the definitive source for the info you're after. The page has info for making KCLO4 and NaCLO4 too, it's all down to the voltage and duration of electrolysys.

Hey Morrigan why don`t you reply on my e-mails anymore??
I have found a source in Holland for KCLO3 plus other chemical`s.
Write me back on sendtosection1@hotmail.com

I've tried lots of different electrodes, copper, stainless steel, carbon, some kind of spoon which im not sure what it was made of and a few other things i have found around the house. Platinum would be too expensive/hard to find.

I can tell you it is worth the effort looking for platinum. With platinum its the fastest way. It isnt too expensive...
I bought it at a specialised company in switzerland. 0,5mm thick platinum sheet cost ~2,15 SFr per g (if you order 50g or more), where 1cm2 = 1,01g. I think thats OK. <a href="http://www.gyr.ch" target="_blank">http://www.gyr.ch</a>

I would rather make it from decomposing hypochlorites by heating them. I'm sick of trying to make it from a cell.

That's another possibility, with access to calciumhypochlorite its fairly easy...
But with sodiumhypochlorite its a real pain unless one could obtain concentrated solution.

I was in Bunnings Warehouse today and they were selling calcium hypochlorate (65% available Cl)10kg or 10L for $45Aus, I cant remember if it was 10kg or 10L because on my comtainer it says L even though it is granules.
