Sodium bromate is mainly used in continuous or batch dyeing processes involving sulfur or vat dyes and as a hair-permagent, chemical agent, or gold solvent in gold mines when used with sodium bromide.
Sodium bromate is produced by passing bromine into a solution of sodium carbonate. It may also be produced by the electrolytic oxidation of sodium bromide. Alternatively, it can also be created by the oxidation of bromine with chlorine to sodium hydroxide at 80 °C.
