Potassium chlorate…

— Posted by The Great Milenko on 3:15 am on Feb. 27, 2002

I recently read through one of my plastic explosive manuals and it had the following recipe that tells you how to make potassium chlorate (btw whats that chemical name for it? just curious) from calcium hypo-chlorate pool chlorine, i was inicially going to try making the famous “chlorate from bleach” method, but you need a hydrometer and it doesnt even seem that it makes that much chlorate, but with this method i dont need a hydrometer and i already have a bigass tub of calcium hypo-chlorate chlorine, all i have to buy is the potassium chloride, so does anyone have anything to say about this b4 i make it? eg: expeiriences, warnings(no doubt) and etc. maybe even zam has somthing to say? :biggrin:
anyway heres the recipe:


This explosive is a chlorate explosive from bleach. This method of
production of potassium or sodium chlorate is easier and yields a
more pure product than does the plastique explosive from bleach
process. In this reaction the H.T. H. ( calcium hypo-chlorate –
CaClO ) is mixed with water and heated with either sodim chlorate
( table salt, rock salt ) or potassium chloride (salt substitute). The
latter of these salts is the salt of choice due to the easy
crystalization of the potassium chlorate. This mixture will need to be
boiled to ensure complete reaction of thc ingredients.
Obtain some H.T.H. swimming pool chlorination compound or
equivalent (usually 65% calcium hypochlorite). As with the bleach
is also a dissociation reaction. In a large pyrex glass or enameled
steel container place 1200 g. H.T.H. and 220 G. potassium chloride or
159 g. sodium chloride. Add enough boiling water to dissolve the powder
and boil this solution. A chalky substance ( calcium chloride ) will be
formed. When the formation of this chalky substance is no longer formed,
the solution is filtered while boiling hot. If potassium chloride was
used, potassium chlorate will be formed. This potassium chlorate will
drop out or crystalize as the clear liquid left after filtering
cools.These crystals are filtered out when the solution reaches room
temperature. If the sodium chloride salt was used this clear filtrate
( clear liquid after filtration ) will need to have all water evaporated.
This will leave crystals which should be saved.
These crystals should be heated in a slightly warm oven in a
pyrex dish to drive off all traces of water ( 40 – 75 deg.C. ). These
crystals are ground to a very fine powder ( 400 mesh ).
If the sodium chloride salt is used in the initial step, the
crystallization is much more time consuming. The potassium chloride is the
salt to use as the resulting product will crystallize out of solution as
it cools. The powdered and completely dry chlorate crystals are kneaded
together with vaseline in plastique bowl. ALL CHLORATE BASED EXPLOSIVES ARE
chloride is used in this explosive, it will have a tendancy to cake and
has a slightly lower detonation velocity. This explosive is composed of
the following:

Potassium or sodium chlorate90 %
Vaseline10 %

The detonation velocity can be raised to a slight extent by the
addition of 2 – 3 % aluminum powder substituted for 2 – 3 % of the vaseline.
The addition of this aluminum will give this explosive a bright flash if
set off at night which will ruin night vision for a short while. The
detonation velocity of this explosive is approximately 32OO M/sec. for
the potassium salt and 290O M/sec. for the sodium salt based explosive.

Not sure… my gut feeling is that you would just get potassium hypochlorite, since I don’t see what would cause extra oxygen to bind to the hypochlorite cation and give you a chlorate… you’d have to add energy to do that (electrolysis?) I think.  But hey, try it… I don’t think it should be overly dangerous & it shouldn’t be awful expensive (

I don know much, but my gut agrees with Zambosan’s gut. From my vague memory of the plastique from bleach and the reaction of like chemicals i think u would need to run an electric current through it at some point. BUT..if it works can u tell me where i can get potassium cloride, not familure with that.

your talking about the ac version it works my friend didd it but it does only make a small amount as tgm said… but if it works out for you man tell me… ill try it..

The only version in the ac that i’m aware of is the chlorate from bleach one, besides the jolly faggot stole all of the recipes in his faggy cookbook from other sites and other manuals so it’s not like it’s actually from the ac, nothing is. I hope your wrong zam, i’d be pissed if this doesnt work, but hey i’ll try it anyway 🙂

i’ve got a book on chlorate- and perchlorate explosives (‘die chloratsprengstoffe’ by ‘dr. richard escales’) and it says that it is possible to get potassium chlorate by mixing solutions of potassium chloride and calcium chlorate and boiling them at low heat. so i don’t see why it wouldn’t work with this H.T.H. compound, too.

— Posted by Zambosan on 1:05 pm on Feb. 28, 2002

Hergor, THAT would certainly get you potassium chlorate, since the chlorate cation from the calcium chlorate would form an ionic bond with the potassium anion from the potassium chloride… HTH is a hypochlorite, however, which carries much less oxygen, making it a poorer oxidizer.  Darkie: potassium chloride is available from most grocery stores as a salt substitute for ppl who are supposed to cut sodium from their diet.

Well if the HTH method would’nt work, were would i obtain calcium chlorate? or perhaps make it?

look for herbicides in garden stores…

I read a procedure in Homemade ammo for making Potassium chlorate.It involves the bubbling of chlorine through a Potassium hydroxide solution.Ive never heard of this procedure before or since as the electrolysis method seems to be the main one.Tried the electrolysis method before but the results were pretty unimpressive.For the amount of effort put in the returns were miniscule.Id imagine the Potassium hydroxide and chlorine method would offer better returns for less effort.

Two questions:
1. I’m dumb, this potassium clorate is a good explosive cause i found some for sale online.(is it a worth while explosive? and is 30g a lot?)
2. Alot of improvised plastique says to mix the base explosive with vasoline. I want to know if melted candle wax would be a good/better alternative. Would it be to hot? Would u then be able to light it with a fuse? cause vasoline sounds yucky!

LOL what a pussie!
Most good plastique binders are 5% wax and 5-1-% vaseline, you could use just wax i spose but it would be shiat, just go buy some vaseline, it’s not like it matters of the checkout chick thinks your gonna use it for lubricant! And no you wouldnt be able to just set it off with a fuse, you need a blast cap and perhaps a booster if your dealing with somthing like anfo, but if your just making chlorate plastique you’ll only need a fairly weak cap like a #3.

sorry about refering to the ac tgm… im reading alot about blassting caps.. could some one tell me a simple way to get them… or a simple way to make them.. and dont tell me to check the archives because im on a mac and they wont work… im on a mac cuz im in school… but could some on help me and tgm im sorry again… but it was only a reference…
