Description

Sodium bromate (CAS 7789-38-0) is an inorganic oxidizing salt used across industrial processing wherever controlled oxidation or bleaching is required. It functions as a selective oxidant, enabling precise chemical reactions in textile treatment and mineral extraction. In water management applications, it serves as a reliable component for specialized treatment protocols. In textile and leather processing, it acts as an oxidative finishing agent, helping to set dyes and improve fiber uniformity.

The compound helps achieve consistent bleaching results in treated fabrics while maintaining material integrity. Gold and silver mining operations use it as an alternative leaching oxidant, supporting the dissolution of precious metals from ore. This application is particularly effective in hydrometallurgical circuits where specific oxidation potentials are required. Pulp and paper producers apply it during bleaching sequences to brighten cellulosic material effectively.

It offers a solution without the process limitations often associated with chlorine-based agents. Water treatment facilities use the chemical as a biocidal oxidant to control microbial growth in industrial water systems. The product is supplied as a white crystalline powder or granular solid for easy handling. It is available in technical grade for industrial applications, with purity levels typically ranging from 99% and above depending on requirements.

Packaging options commonly include 25 kg bags or drums to suit different facility needs. Bulk quantities are available for large-scale industrial procurement and long-term supply chain stability.
