chemical formula: KClO3
( fine powder )
Potassium Chlorate is a powerful oxidizer used in older pyrotechnic formulations.
Mixed with Manganese Dioxide in a test tube and heated, it can conveniently be used to
produce useful quantities of pure Oxygen gas for other experiments. Potassium Chlorate is an unstable oxidizer. Pyrotechnic mixtures made with it are prone to spontaneous
combustion and decomposition. For this reason it is banned from most
firework formulations - generally being replaced with the far more
stable Potassium Perchlorate.
Potassium Chlorate requires
care when mixed with other chemicals as they may become friction or
static sensitive, and could ignite without warning.
