Potassium chlorate is a common inorganic compound with the chemical formula KClO₃. At room temperature, it appears as colorless flaky crystals or white granular powder, with a cool salty taste. It is soluble in water, forming a neutral aqueous solution, and slightly soluble in ethanol. It serves as a widely used chemical raw material in laboratory tests and industrial production.
Its key property is strong oxidizing capacity. It remains stable under normal temperature. When heated above 400℃, it decomposes and releases oxygen, which is the principle for oxygen preparation in chemistry laboratories. With manganese dioxide as catalyst, it decomposes rapidly to generate oxygen. Thanks to its simple operation, it is a common reagent for oxygen production experiments in middle school chemistry.
Industrially, potassium chlorate has a wide range of applications. It can be used for match heads, pyrotechnic compositions, as well as bleaching agents for paper-making, oxidants for printing and dyeing, and raw materials in metallurgy and pharmaceutical intermediate synthesis. With upgraded safety standards, more stable perchlorates have gradually replaced it in some flammable and explosive scenarios for safer chemical operations.
