Sodium Chlorate

Product information

Molecular Formula: NaClO₃

Molecular Weight: 106.44 g/mol

H.S. Code: 2829.11.00

EINECS: 231-887-4

CAS Number: 7775-09-9

Characteristics: It is colorless crystal or white particle at room temperature. No smell. Oxygen is released at about 300 ºC and decomposed at higher temperature.

It has strong oxidizability. Friction or impact with organic or reducing substances can cause burning or explosion. Low toxicity, LD50 (rat, oral) 1200mg / kg.

Applications & Uses:

1. Pulp & Paper Industry

Bleaching Agent: Primary raw material for generating chlorine dioxide (ClO₂), a key eco-friendly bleaching agent for wood pulp and paper production.

Delignification: Removes lignin from cellulose fibers to enhance paper brightness and strength.

2. Water Treatment

Disinfection: Generates chlorine dioxide for municipal drinking water and wastewater treatment to eliminate pathogens and control biofilms.

Cooling Systems: Prevents microbial growth in industrial cooling towers.

3. Agriculture

Herbicides: Active ingredient in non-selective herbicides (e.g., sodium chlorate-based weed killers for pre-harvest crop desiccation).

Soil Sterilization: Controls invasive weeds in non-crop areas.

4. Chemical Synthesis

Oxidizing Agent: Used in the production of perchlorates, chlorites, and other specialty chemicals.

Dye Manufacturing: Facilitates oxidation reactions in synthetic dye intermediates.

5. Mining & Explosives

Ore Processing: Oxidizes sulfide ores in metal extraction (e.g., uranium, gold).

Explosive Compositions: Component in pyrotechnic mixtures and ammonium perchlorate-based explosives.

6. Textile Industry

Fabric Bleaching: Whitens textiles and removes natural impurities from cotton and linen.

7. Electrochemical Applications

Oxygen Candles: Source of oxygen in emergency breathing systems (e.g., submarines, aircraft).

8. Metal Surface Treatment

Metal Etching: Cleans and oxidizes metal surfaces in electroplating and anodizing processes.

9. Pharmaceuticals

Intermediate: Used in niche synthesis of iodine-based contrast agents and antiseptics.

10. Miscellaneous Uses

Matches & Pyrotechnics: Oxidizer in safety matches and colored flare compositions.

Laboratory Reagent: Standard oxidizer in analytical chemistry.
