Potassium Chlorate
Potassium chlorate is a chemical compound that contains chlorine, oxygen, and potassium. In its pure form, it is white and crystalline in appearance. It is the most common chlorate used in industry, school, research, and commercial labs. Potassium chlorate is commonly used: to prepare oxygen, in safety matches, as an oxidizing agent, in fireworks and explosives, and in fruit cultivation.
Potassium Chlorate Uses
Potassium chlorate was originally one of the key ingredients in firearm percussion caps or primers, and is still infrequently used in this way today. It is more commonly used in fireworks production currently, which include noise makers and other popular novelty fireworks. Potassium chlorate is also used in plastic explosives, gunpowder, and laboratories to produce oxygen. It is also used in chemical oxygen generators or chlorate candles, which serve as the oxygen-supply system for space and underwater craft.
How is Potassium Chlorate Produced?
For major potassium chlorate commercial production, sodium chloride is electrolyzed. This results in the formation of sodium chlorate, which is then reacted with potassium chloride, creating potassium chlorate. The substance can also be produced on a small scale. This is done when hypochlorites undergo thermal disproportionation and become a chlorate, which is then boiled until it becomes a chloride. At this point, Kcl is added to the mixture. Chlorine and chlorine dioxide gas are byproducts of this mixture, therefore this process should be conducted in a properly ventilated lab environment.
Potassium Chlorate Safety
Because potassium chlorate often has an extreme reaction when it comes in contact with many materials, it has to be handled with care. The substance is known to ignite or explode spontaneously, and can significantly burn anything it comes in contact with when combined with a combustible material. If potassium chlorate is mixed with sulfuric acid or any other fuel, it will ignite. Fireworks created with potassium chlorate deflagrate if sulfur is mixed with them. If the substance is mixed with any flammable compound, the result will be extremely shock intensive.

- Potassium Perchlorate
Potassium Perchlorate (Potassium Chlorate (VII), perchloric acid, potassium salt, peroidin, and KClO4) is an inorganic salt that is used as a strong oxidizer. The function of potassium perchlorate’s oxidizer trait really depends on the chemical use. Potassium Perchlorate can be found in the following common items: Fireworks – Fireworks have many chemical compounds inside them, [...]...
- Potassium Benzoate
Potassium benzoate is the potassium salt of benzoic acid. Benzoic acids are weak acids that are used as food preservatives. Potassium benzoate is also commonly used for preserving food. It is primarily used to inhibit mold and bacteria growth. This allows the product that potassium benzoate preserves to last longer on the shelf, thereby increasing [...]...
- What Does Potassium do for the Body?
Potassium is an essential mineral that the body uses to perform various functions. The body naturally regulates the amount of potassium in the body to keep it in working order. This is done by the kidneys, the bowels and even natural processes such as sweating. Eating a diet which incorporates the recommended amount of potassium supplementation is best [...]...
- Potassium Gluconate
Potassium is a mineral that is found naturally in many foods. It is one of the most important minerals as it helps the body to carry out many different functions, the most important being its use in the beating of the human heart. In some cases, it is difficult for people to get enough potassium [...]...
- Oxygen Generators
An oxygen generator is a device that produces oxygen on demand, usually through the use of inorganic reactions. There are several types of oxygen generators but each depends on thermal reactions to produce oxygen. This causes the generator to become very hot, between 500 and 1,200 degrees Fahrenheit, and can present a serious fire hazard [...]...
