What is Sodium bromate?
Sodium bromate (CAS 7789-38-0) is an inorganic oxidizing salt used in industrial processing where controlled oxidation or bleaching is required.
Where is Sodium bromate used?
- Textile and leather: oxidative finishing agent that sets dyes and improves fiber uniformity
- Textile bleaching: consistent results while maintaining material integrity
- Gold and silver mining: alternative leaching oxidant for dissolution of precious metals from ore
- Hydrometallurgical circuits: effective where specific oxidation potentials are required
- Pulp and paper: applied during bleaching sequences to brighten cellulosic material
- Water treatment facilities use the chemical as a biocidal oxidant to control microbial growth in industrial water systems.
Commercial specifications
- Technical grade, purity typically 99% and above depending on requirements
- Packaging commonly 25 kg bags or drums
- Bulk quantities for large-scale procurement
