용도
개요
Barium bromate is used extensively to form other bromates, including the alkali metal bromates which are used extensively in Industry. HBrO3, a colorless liquid, is made by the addition of dilute sulfuric acid to barium bromate. It dissociates extensively in aqueous solution and is a strong acid. The scientific literature contains a few studies of barium bromate chiefly due to interest in Industry for its use to prepare other bromate salts. This salt is available commercially, worldwide.
용도
Barium bromate [Ba(BrO3)2] is used as a corrosion inhibitor to prevent rust and as an oxidizing agent and chemical reagent.

제조 및 합성 방법
제조 방법
Barium Bromate may be prepared by reaction of the hydroxide with sodium bromate: Ba(OH)2＋ 2NaBrO3→Ba(BrO3)2＋ 2NaOH Barium bromate is relatively insoluble, and has a value of 0.782 g/100 ml of water at 298 K,if recrystallized, it forms a monohydrate, Ba(BrO3)2·H2O, which occurs as white or colorless, prismatic crystals. A new and general method of inducing a precipitation from homogeneous solution has been applied to the separation of barium and strontium. The precipitation of barium bromate, a water-soluble compound, is brought about by a gradual change in the composition of the solvent media. An organic compound, such as methanol or tetrahydrofuran, is allowed to diffuse into the original water solution, thus slowly converting the solution into a water organic mixture. Strontium bromate is about 40 times more soluble in water than barium bromate. The increased solubility plus the greater stability of the strontium MEDTA chelate tend to hold the strontium in solution. The chief advantage of this method over the separation of Sr from Ba by precipitation of barium chromate is in the preparation of barium compounds. Usually, barium must be separated from the chromate before proceeding. However, barium bromate can be easily converted to the oxide, eliminating this separation step.
