$8.75 Per Pound / 2 Pound Bags

Perchlorate is the inorganic salt with the chemical formula KClO4 and is a very common oxidizer in pyrotechnics.  Pyrotechnicians use Potassium Perchlorate for making colorful stars and flash powder.

SKU: FCB148 Category:


Composition based on Potassium Perchlorate tends to be less sensitive than those based on chlorates.  Perchlorates can be used with sulfur and sulfides.  For these reasons, it is much preferred above chlorates.  This is a strong oxidizer although it usually reacts very slowly with organic substances.  Perchlorate is a common oxidizer used in fireworks, ammunition percussion caps, explosive primers, and is used variously in propellants, flash compositions, stars, and sparklers.

Potassium perchlorate must be stored away from any strong mineral acid as well as any reducing agent, in sealed bottles. As it is not hygroscopic, it does not require dry environment. Any clean plastic bottle or bag can be used as a storage container.

According to the certificate of analysis 99% passes a 325 mesh screen, purity is at 99.2% or better.  This means it’s ready to go out of the container with no further processing needed.

This Potassium Perchlorate contains a small amount of Cabosil to help minimize clumping and keep the mixture free-flowing.

Perchlorate is moderately toxic, can be absorbed through the skin and breathing protection should be worn when handling fine powder.

    I’ve purchased P.P. from every retailer that offers it for sale online. This is by far the highest quality and its an extremely fine and free flowing “clump” free chemical, versus the typical chunky chemical in need of further processing that most other retailers are peddling. Fireworkscookbook doesn’t drag their feet in getting orders out the door. Don’t waste your time looking elsewhere, you’ll never find better product for any price and you’ll never find a more trustworthy place to purchase the majority of your firework related needs. Thanks again!
