Potassium chlorate is a salt that comes in form of small colorless crystals at standard conditions. Potassium chlorate is mostly used as a disinfectant, as an oxidizing agent, in the production of matches, other pyrotechnic products and explosives. It is also used as an oxygen generator, since it produces oxygen (and potassium chloride) upon thermal decomposition. This property is often used in various aircraft, submarines and spacecraft.

Potassium chlorate is one of the substances that are relatively difficult to come by. At the moment, the best idea might be to try to order this substance from chemical selling companies, although such companies mostly sell only larger amounts of this compound.
