Comments are moderated before they will appear on the website, this is a manual process and may take some time. Please be patient.
Author Name is a required field.
Email Address is optional, but without one I won't be able to contact you back. It is never shown or linked on the website. You can always just email me if you'd rather not post a public comment. I generally reply in-line with a comment rather than email you back, unless I want to discuss something in private or off topic. Please check back to see when I reply.
Website URL is optional, if supplied the Author Name will be hyperlinked to this URL.
You may use wikitext in the body, preview may be handy here. Don't worry if you can't figure them out, just give me a hint what you want linked to what and I'll do it during moderation. Wikitext is not BBcode!
Spammers: Please don't bother wasting your time scripting up posts to this form. Everything is moderated, your post will never be seen on the web even transiently, there is no way to even view it by its internal ID, it will never be indexed. I will simply delete your post in the moderation interface. If I'm your target audience you're really on the wrong track; I'll never click on a URL in your garbage. The post content is not emailed to me (and I don't use a Win32 mail client anyway), I view the posts in plain text in the moderation interface so no clever tricks of any kind will make anything you type be interpreted by anything other than me, a human. Just give up and go elsewhere please!

Seems like you are using PS (Polystyrene) jar!PS is totally transparent and PS cannot resist chemical corrosion.Try use HDPE .It is opaque and white in colour.I always use this type of container to make chlorates,and even store 98% Sulphuric Acid in it.But be careful, the temperature cannot exceed 85C,or else it will melt like wax....

Hi Alan.My question is, can I seal the whole thing with silicone rubber(sealant)to create some "pressurized" effect in order to reduce chlorine loss and water loss?

Hello Alan,
in my experiments PVC workeed well for a cell container. However I had problems with tubing connectors that were probably made of PE. I finally machined them from PEEK and PTFE what may be an overkill, PVC may have worked as well.

Thomas, thanks mate. :)
Glad to hear your KClO3 production went well. It is surprisingly easy isn't it? Once you've got a suitable anode material and a power supply, all it takes is a bit of patience. Especially for Potassium Chlorate, others (and Perchlorates) take a few more steps, but with KClO3 all you need is purification at the end of the run.

Fabulous website! I refered to your pages while making my chlorate cell. (I used an MMO mesh anode designed for cathodic protection of steel and stainless steel cathode in KCl solution. 140g after 4 days and about 288Ah for the first run.) You amaze me with the amount of projects you successfully complete! Electronics, pyrotechnics, software, metal casting.. very impressive!

Jack,
I can't remember how much I was quoted to tell you the truth, but they weren't cheap. Ti-Anode was the company, they still spam me to this day.
Removing graphite is a huge pain, but I find it best to allow the solution to settle out and decant as much as possible without disturbing the graphite at the bottom. This reduces the filtration burden, but you still need to filter it, maybe several times and with stacked papers if you are using coffee filters.
The muddy mess left from the decanting can be filtered slowly, maybe taking hours, through the best filters you have. Alternatively you can simply throw it out depending on how much solution it represents.
It all takes a lot of time unless you have a vacuum filtration system, and even then you need to use high-quality papers.
Regards,
Alan

You said that you were getting a quote about anodes from a supplier in India. Could you tell me what their price was? And if the company is Titan? I'm from South Africa, and getting desperate for good anodes. How do you get graphite particles out of your solution?
