Sodium perchlorate is hardly ever used in pyrotechnics, since it is very hygroscopic. It finds occasional use in composite rocket propellants. It is however very usefull as a starting point in the preparation of several other (less hygroscopic) perchlorates for which reason it is included here.
Sodium perchlorate can be prepared at home. It involves electrolysing a sodium chloride solution under certain circumstances. A description of the process, cell and anode design, etc. for home produciton may be found in the chlorate and perchlorate section of this page.
Sodium perchlorate is toxic, and breathing protection should be worn when handling fine powder.
