Anyone know how to get Potassium Chlorate simply using chemical processes?(as opposed to simply buying it)?

Another one...

There is a good method posted on: (just read up to "Powder these to the consistency of face powder, and heat gently to drive off all moisture.")

This basically describes taking bleach heating it, adding potassium chloride (easy-to-buy salt substitute), cooling the solution, and filtering it.

Heating the bleach causes the NaClO (sodium hypochlorite) to decompose into NaCl (table salt) and NaClO3 (sodium chlorate). Upon the addition of the KCl (potassium chloride), the NaClO3 and KCl undergo and double displacement reaction creating the KClO3.

3NaClO ---> 2NaCl + NaClO3

NaClO3 + KCl ---> KClO3 + NaCl

The method was easy and successful for me, but if worst comes to worst, do a Google search and it will point you in the right direction.

Quoted from

When it comes to explosives Potassium Chlorate is a must have. Its easy to make, and the ingredients are easily obtainable.

Ingredients/ Materials:

Potassium Chloride (Health Salt)
HTH Pool Chlorinating Compound.
Pyrex Glass Container
Glass Pan
Heat Source
Two Buckets
Large piece of Thick Cloth
A place Outside

Boil some Water inside on either the stove, or in the microwave. Pour that water into your Pyrex glass container, take it outside and boil it on your heat source.
Using a ratio of 1:6 measure out one part Potassium Chloride, and six parts HTH.
Slowly add the HTH to the boiling water, and stir it in until dissolved. When the HTH has been dissolved add in your Potassium Chloride.
Boil this mixture for about 5 minutes. While boiling a chalky substance will be formed, this is Calcium Chloride and can be filtered out.
Do not breath in the fumes, or splash in eyes!
To make a filter take one of the buckets and punch enough holes in the bottom so tht the liquid will drain through quickly, then take your Cloth and set it on the bottom of the bucket and up the sides.
When the filter has been made hold it over the other bucket and filter the liquid while it is still boiling.
When the liquid has been filtered pour it back into the glass dish and boil for another minute, then place it in a cool spot and allow the crystals to condense out of the water.
Pour the water off, and spread the crystals around on a glass pan to dry.
Do not use any metal pan as the moisture from the crystals, and the crystals themselfes will eat through it!
Because Health salt is a 50-50 mix of KCl and NaCl, both Potassium Chlorate and Sodium Chlorate are produced. To obtain the Sodium Chlorate simply evaporate the water from the liquid, and collect the remainin crystals.
CAUTION: Potassium Chlorate is sensative to heat, shock, and Friction. These should be avoided!
When the crystals have dried place them in a Dry Air Tight Container, preferably out of the sun.

Note from me: It says to remove the Sodium Chlorate, simply evaporate the remaining water - this would only remove the water, not the sodium - so its not a pure is your friend.
HTH Pool chlorinating compound is the same as chlorine tablets right?
It contains whatever is on the box (check the MSDS).
After rereading through that short guide several times after reading the note from you, it sounds like a misunderstanding. It says to collect the crystals, then to get sodium chlorate, to evaporate the water and collect the remaining crystals.

I'm not sure if you have tried this procedure before or not, but it sounds like the crystals that form while cooling are pure (or close to it) potassium chlorate, and that the way of OBTAINING (it says obtain, not remove) sodium chlorate is by evaporating the water.

So the liquid contains water, potassium chlorate and sodium chlorate. When you take out the crystals after cooling, you are taking out the potassium chlorate. When you then evaporate the liquid, the water leaves and the remaining crystals are sodium chlorate.

So if I read that correctly (and I did read it thoroughly several times), as long as you remove the crystals after cooling, before the liquid has any chance of evaporating a noticeable amount of water, the crystals will be potassium chlorate, and the sodium chlorate will still be dissolved into the water.
Those were excerpts from the linked articles - I've not personally done it, just the phraseology makes it seem that way...I totally see where you're coming from.
Well I'm going to probably try this out later this month.
In addition, I'll be using a method of creating phosphorus I heard of, then making red phosphorus.
If the phosphorus experiment doesn't work, I'll just ball mill aluminum foil and make flash powder rather than Armstrong Mix.
Either way, I'll try out that method of creating potassium chlorate, and I'll reply with the results

actualy its better to use potassium sulfate and calcium hypochlorite as it makes calcium sulfate, which will drop out of the water , plus its filterable , not like sodium chloride
