Calcium bromate, Ca(BrO3)2, is a calcium salt of bromic acid. It is most commonly encountered as the monohydrate, Ca(BrO3)2•H2O.[citation needed]
It 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.[citation needed] In theory, electrolysis of calcium bromide solution will also yield calcium bromate.
It is used as a bread dough and flour "improver" or conditioner (E number E924b) in some countries.[3]
