Chlorates and perchlorates Chlorate and Perchlorate Manufacturing at a Small Scale Introduction Chlorates and perchlorates are among the most often used oxidisers in pyrotechnics. BaClO 3 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. The amateur pyrotechnist can prepare chlorates and perchlorates at home with some effort.
