| | Chlorates and perchlorates are among the most often used oxidisers in pyrotechnics.
Especially potassium perchlorate, KClO4, potassium chlorate KClO3, ammonium perchlorate, NH4ClO4, and barium chlorate
BaClO3 are used extensively. Chlorates and perchlorates are chemically related but from a pyrotechnical standpoint
perchlorates are generally safer to use. Chlorates require special handling. Mixtures made with tend to be more sensitive
than similar mixtures based on perchlorates and some may ignite spontaneously. Potassium chlorate is extensively used
commercially since it is cheaper than potassium perchlorate, and many accidents have happened that might have been
prevented if the corresponding perchlorate was used instead. The use of chlorates is therefore not recommended. If you
do decide to use them, make sure you really understand what you are getting involved with.
