Lithium bromate, LiBrO₃, is the lithium salt of bromic acid.

Preparation

Lithium bromate is usually prepared by the electrolysis of lithium bromide solution at 65–70 °C, in the presence of dichromate and using anodes of lead dioxide or iron and cathodes of stainless steel or copper. The lithium bromate can be crystallized by cooling the electrolyte, and any unoxidized bromide recycled.

Lithium bromate can also be prepared by reacting bromine with lithium hydroxide solution at 50–90 °C.
