Sodium chlorate (NaClO3) is a powerful oxidizing agent with various industrial, agricultural, and laboratory uses. Here are its main applications:
Industrial Uses
1. Bleaching Agent in the Pulp and Paper Industry
• The primary use of sodium chlorate is in the bleaching of wood pulp (especially in the Elemental Chlorine-Free or ECF process).
• It’s used to produce chlorine dioxide (ClO2), a selective and environmentally friendlier bleaching agent.
2. Chemical Manufacturing
• Used as an oxidizer in chemical synthesis.
• In the production of dyes, explosives, and other chlorate compounds.
Agricultural Uses
3. Herbicide/Weed Killer (now largely restricted or banned in many countries)
• Formerly used as a non-selective herbicide to kill weeds and unwanted vegetation.
• Banned or heavily regulated in places like the EU due to tox
