| Hazard Information | Back Directory | [Chemical Properties]
Barium bromate is a white crystalline powder. | [General Description]
A white crystalline solid or powder. Slightly soluble in water and denser than water. Very toxic by ingestion or inhalation. Fire hazard when in contact with organic materials and may explode when heated above 300°F. Used as a corrosion inhibitor and to manufacture other chemicals. | [Reactivity Profile]
BARIUM BROMATE(13967-90-3) is an oxidizing agent. May react violently with combustibles and reducing agents such as textiles, oil, fat, sugar, sawdust, ammonium salts, sulfur, carbon, phosphorus, metal powders and sulfides. A combination of finely divided aluminum with finely divided BARIUM BROMATE(13967-90-3) can explode by heat, percussion, or friction [Mellor 2:310 1946-47]. | [Air & Water Reactions]
Slightly soluble in water. | [Hazard]
A poison. Moderate fire risk in contact with
organic materials.
| [Health Hazard]
Toxic by ingestion. Inhalation of dust is toxic. Fire may produce irritating, corrosive and/or toxic gases. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution. | [Potential Exposure]
This material is used as an analytical
reagent, oxidizer and corrosion inhibitor. | [Fire Hazard]
These substances will accelerate burning when involved in a fire. May explode from heat or contamination. Some may burn rapidly. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts
the skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from
exposure, begin rescue breathing (using universal precautions,
including resuscitation mask) if breathing has
stopped and CPR if heart action has stopped. Transfer
promptly to a medical facility. When this chemical has

been swallowed, get medical attention. Give large quantities
of water and induce vomiting. Do not make an unconscious
person vomit. See also First Aid section in
“Barium” entry. | [Shipping]
UN2719 Barium bromate, Hazard Class: 5.1;
Labels: 5.1—Oxidizer, 6.1—Poisonous materials. | [Incompatibilities]
A strong oxidizer; keep away from
reducing agents. Keep away from oxidizable materials; aluminum,
arsenic, carbon, copper, metal sulfides; phosphorus,
sulfur, organic, and combustible materials (such as wood,
paper, oil, fuels), since violent reactions occur. | [Description]
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. | [Preparation]
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. | [storage]
Color Code—Yellow: Reactive Hazard; Store in alocation separate from other materials, especially flammablesand combustibles. Store in tightly closed containers in a cool,well-ventilated area. Sources of ignition, such as smokingand open flames, are prohibited where barium bromate ishandled, used, or stored. Avoid any possible contact withincompatible materials. See OSHA Standard 1910.104 andNFPA 43A Code for the Storage of Liquid and SolidOxidizers for detailed handling and storage regulations. |
