1. Performance and use:

The bromates of chief industrial interest are those of sodium and potassium. Sodium bromate is used in mixtures with sodium bromide to extract gold from ore. It is also used as an analytical reagent, as a cleaning agent for boilers, and as a component in hair-waving formulations. Potassium bromate is used primarily as a conditioner for flour and dough; some of its nonfood uses include use as an oxidizing agent for analytic chemistry and as a brominating agent. The bromates of calcium and barium have limited use as oxidizers, maturing agents in flour, and analytic reagents.

Sodium bromate is used as an oxidant to convert tetrahydropyranyl ethers to carbonyl compounds. It acts as an analytical reagent. It is also used for dissolving gold from its ores, boiler cleaning, oxidation of sulfur and vat dyes. Further, it is used in hair treatment formulations as a hair-permanent.

As a mixture with sodium bromide for dissolving gold from its ores.
