Not hygroscopic.
Under the influence of acids splits off explosive chlorine dioxide, in the presence of which many organic materials ignite spontaneously.
One of the most active oxidizers in pyrotechnics.
It has a low decomposition temperature, compositions based on it have lower ignition temperatures.
In its pure form, it can explode from a very strong impact, but does not detonate from a No.6 blasting cap.
Decomposition catalysts: manganese dioxide, potassium dichromate, copper oxides.
Incompatible with ammonium salts, because In the presence of moisture, it forms unstable ammonium chlorate, which is prone to spontaneous combustion (such compounds are prohibited by law in the USA).
When mixed with dry phosphorus, it explodes even under minimal compression.
It is not recommended to use potassium chlorate together with metals such as magnesium and aluminum due to the high sensitivity and activity of such mixtures.
Compositions containing it should not be allowed to grind in dry form.
Caution is required when mixing with sulfur-containing substances.
Potassium chlorate is obtained by electrolysis of a solution of potassium chloride on carbon electrodes in the presence of potassium dichromate; by chlorination of a heated aqueous solution of slaked lime. The resulting calcium chlorate is mixed with a solution of potassium chloride, after which potassium chlorate crystals precipitate.
Toxic. The lethal dose for humans is over 50 mg/kg.
First obtained by Berthollet in 1786.
