The bitartrate method is a candidate for production and can be used if exotic chlorates are currently inaccessible or need to be synthesized.
On heating, ammonium chlorate decomposes at about 102 °C, with liberation of nitrogen, chlorine and oxygen.
This compound is a powerful oxidizer and should never be stored with flammable materials, as it can easily form sensitive explosive compositions.
Ammonium chlorate is a very unstable oxidizer and will decompose independently, sometimes violently, at room temperature.
[1] This results from the mixture of the reducing ammonium cation and the oxidizing chlorate anion.
