Structure: Crystal structure
The chemical formula of KClO3 is a crystal structure called chlorate wax or oxygen wax. It is in the category of propellants as chlorates. It can be expensive. It has a very strong oxidizing properties. It is a suitable source for producing oxygen gas in educational institutions.
Production and Reactions
Potassium chlorates can be obtained by reacting with sulfuric acid to form a highly reactive solution of chloric acid and potassium sulfate.
2 KClO3 + K2SO4 + H2SO4? 2 HClO3
Potassium perchlorate can be converted by heating in the absence of a catalyst.
4 KClO3? 3 KClO4 + KCI
With more heating, potassium perchlorate may decompose into potassium chloride and oxygen.
KClO4? KCl + 2 O2
O2 gas can be obtained by reacting potassium chlorate with manganese (IV) oxide.
KClO3 + MnO2? KCl + 3/2 O2
Potassium chlorates are used as a kind of insecticide. The production of this medicinal product called as phagabit was started in Finland and found its use in Europe.
It is used as a source of oxygen in the aircraft industry.
The production of sprengel explosives with a suitable fuel is provided. It also finds use in mine production.
