1. Fireworks and Explosives
Fireworks/Fireworks
As an oxidizer, it provides the oxygen needed for combustion and generates colorful flames . It is often mixed with sulfur, charcoal, and metal powders to make flash powders or explosive materials.
Explosives and Matches
Detonating fuse: Combined with perchlorates or azides, used for mining blasting.
Match head: In traditional "friction matches", potassium chlorate is contained, but modern safety matches have gradually been phased out .
2. Chemical Synthesis and Laboratory Uses
Oxidants
Used for preparing oxygen, commonly found in middle school experiments.
In organic synthesis, oxidizing alcohols, sulfides, etc.
Bleaching and Disinfection
Originally used for textile bleaching, but decreased due to the emergence of substitutes such as sodium hypochlorite; it can also be used as a disinfectant to treat wastewater or laboratory equipment.
3. Agriculture and Horticulture
Herbicides
Inhibiting the growth of mosses and algae, destroying plant cells through oxidation.
At high concentrations, it acts as a non-selective herbicide.
