Pure potassium perbromate is stable up to 275°, at which temperature it decomposes to potassium bromate. The impure product may undergo partial decomposition at lower temperatures. 

Silver perbromate, AgBr04.—The perbromate is prepared by double decomposition from potassium perbromate and silver nitrate, and is but slightly soluble in cold water. 

The synthesis of HBr04 and rubidium and potassium salts was accomplished, using oxidation of bromate by XeF2 or (preferably) molecular fluorine in aqueous solution.19 Spectral studies20 show that the perbromate ion is tetrahedral in both the solid-state and aqueous solutions. The thermodynamic properties and thermal decomposition of individual salts are discussed under each element. A more general article on various properties of the perbromates was published by Herrell and Gayer.21...
