How do I make potassium chlorate?

Buy 2 MMO coated titanium plates. You can find those on eBay sometimes. I got a great deal a while back, got a 36″ x 12″ plate for $36. Then buy a bag of sodium free water softener salt. Make sure the bag says it's 100% potassium chloride. Make a saturated KCl solution, put that in a large glass jar, and put 2 of those MMO electrodes in the solution,make sure they aren't touching. Then connect the leads to 3.3–5v power supply. Old PC power supplies work great. Let the cell run for a couple of weeks, you can also make a basket and fill it with chunks of KCl and leave that in the cell, as KCl gets converted to KClO3 more KCl from the basket will dissolve, increasing yeild. The KClO3 will drop out of solution as it forms. After a couple weeks, put the jar in the freezerChina Vacuum Filter Belts Manufacturers to crash out as much KClO3 as possible. Then pour off the liquid and rinse the crystals with cold water to remove KCl contamination. If you want a higher purity. Take the washed KClO3 cystals and dissolve as much as you can in boiling water. Cool the solution and filter out the crystals that form. There are plenty of ways to optimize this reaction, like controlling pH and temperature, but I never found this necessary. The only thing I make sure of is that the solution is over 55°C during electrolysis. This is never a problem, because you should Nonwoven Forming Belts Suppliers be pushing over 10+ amps into the solution. If you aren't pushing enough amps or the solution is not hot enough, just move the electodes closer together and make sure your power supply is rated at least 20 amps at 5v. One last thing, you may want to set this up outside, because it makes Chlorine gas, most of which dissolves and reacts with the KCl, but even worse is the salt spray that forms, you will get salt mist on everything. I usually just put a lid on the jar with a hole in it, then I put a plastic tube in that hole and lead it into a jar of water or out a window, that keeps that salt mist from destroying everything in my room.
