Calcium bromate, Ca(BrO3)2, is a calcium salt of bromic acid.
Calcium bromate is most commonly encountered as the monohydrate, Ca(BrO3)2•H2O.
Calcium bromate can be prepared by reacting calcium hydroxide with sodium bromate or calcium sulfate with barium bromate. Above 180 °C, calcium bromate decomposes to form calcium bromide and oxygen. In theory, electrolysis of calcium bromide solution will also yield calcium bromate.
Calcium bromate is used as a bread dough and flour "improver" or conditioner (E number E924b) in some countries.

Calcium Bromate is generally immediately available in most volumes.
Calcium dibromate belongs to the class of inorganic compounds known as alkaline earth metal bromates. These are inorganic compounds in which the largest oxoanion is bromate, and in which the heaviest atom not in an oxoanion is a lanthanide. Based on a literature review very few articles have been published on calcium dibromate.

Chemical Properties
white, monoclinic, crystal(s) powder(s); oxidizing agent; used as a maturing agent, a dough conditioner
Uses
Calcium bromate is used as a maturing agent and dough conditioner in bromated flours.Other than this usage, this salt is not utilized in Industry.
Calcium Bromate is available commercially.
Uses
Calcium Bromate is a dough conditioner and maturing and bleaching agent which exists as a white crystalline powder.
it is very soluble in water and is used in flour and dough.
Preparation
Calcium Bromate may be prepared by reacting calcium hydroxide with sodium bromate or by reacting calcium sulfate with barium bromate:
Ca(OH)2＋ 2NaBrO3→Ca(BrO3)2＋ 2NaOH
CaSO4 (aq)＋ Ba(BrO3)2 (solid)→Ca(BrO3)2 (aq)＋ BaSO4 (solid)
Of the two methods, the latter seems to be more stable one since the temperature can be as high as 80°C in solution. The usual product is a monohydrate, Ca(BrO3)2·H2O.
Calcium bromate monohydrate occurs as colorless, monoclinic crystals or prismatic plates which are soluble in water. This salt loses its water below 180°C and decomposes above that temperature to form calcium bromide plus oxygen.
Calcium bromate is a salt of bromic acid and lime.
Calcium bromate may be prepared by the anodic oxidation of calcium bromide.
Calcium bromate is used as a flour improver in some countries.
Calcium bromate, Ca(BrO3)2, is a salt of bromic acid and lime.
Calcium bromate may be prepared by the anodic oxidation of calcium bromide.
Calcium bromate is used as a flour improver (E number E924b) in some countries.
Calcium bromate, Ca(BrO3)2, is a bromic acid calcium salt.
Calcium bromide is hygroscopic and colorless crystals with a harsh saline taste in its anhydrous form.
Ca(BrO3)2•H2O is the most usually found monohydrate. One calcium atom and two bromine atoms combine to produce it.
Many reactions can occur with calcium bromide. The synthesis of calcium oxide from calcium bromide and oxygen gas is useful in the chemical industry. This reaction, which produces bromine gas at high temperatures, occurs at high temperatures.

Dissociation
Calcium bromide is a hygroscopic, colorless crystal with a harsh saline taste in its anhydrous form.
Calcium bromide is water and alcohol-soluble.
Calcium bromide’s made by combining calcium carbonate (CaCO3) and calcium oxide with hydrobromic acid (HBr).
Calcium bromide can also be produced by reacting calcium metal with elemental bromine.
Application
