  • Description Potassium chlorate is an important compound that is widely used in various fields, including chemical industry, agriculture, medicine, etc. It is one of the first component used in the production of fireworks because of its explosive nature, where it serves as a oxidizer, which plays an important role in burning the firecracker at a fast rate. And the oxidizing property makes it an component of smoke composition to produce smoke grenades. It also shows a disinfectant effect, commonly used for preparing chlorine dioxide, a effective disinfectant that is often applied to water for eliminating bacteria, viruses, protozoa and odor-causing compounds. Besides, in the laboratory, potassium chlorate can be decomposed into oxygen, which is a far inexpensive source than a pressurized or cryogenic oxygen tank. Therefore, it can be used in medicine to treat pneumonia as well as gas poisoning, and employed as oxygen-supply system of aircraft, space stations, submarines, etc. Studies have proved that potassium chlorate is helpful in the cultivation of dormant tree, such as Longan trees to increase the yield of fruits when treated with potassium chlorate. Potassium chlorate, is a transparent, colorless crystal or white powder. It is soluble in boiling water and decomposes at approximately 750°F (398°C), giving off oxygen gas. Potassium chlorate is a strong oxidizer and forms explosive mixtures with combustible materials, such as sugar, sulfur, and others. Potassium chlorate is incompatible with sulfuric acid, other acids, and organic material. The four-digit UN identification number is 1485. Its primary uses are as an oxidizing agent in the manufacture of explosives and matches; in pyrotechnics; and as a source of oxygen. Sodium and potassium chlorates have similar properties. Chlorites are powerful oxidizing agents. They have one less oxygen than the base-state oxysalts. They form explosive mixtures with combustible materials, and in contact with strong acids, they can release explosive chlorine dioxide gas.
  • Uses It is used for source of oxygen. Explosives; fireworks; matches; printing and dyeing cotton and wool black; manufacture of aniline black and other dyes; source of oxygen; in chemical analyses. Potassium Chlorate is used in micro-smoke cold fireworks containing bright bead. Used (1) in matches, (2) in pyrotechnics, (3) as disinfectant, (4) as a source of oxygen upon heating. (Hazardous! Use of potassium perchlorate is recommended instead.)
