A substantially dried XF.cndot.nH.sub.2O.sub.2 product is produced by method(s) wherein a feed solution comprised of (i) a XF composition wherein X is K, Na.sup.+ or NH.sub.4.sup.+ and n is an integer from 1 to 3, (ii) hydrogen peroxide (H.sub.2O.sub.2), (iii) a fluid carrier component and (iv) a potassium bifluoride (KHF.sub.2) catalyst, is atomized as it enters a desiccation/evaporation chamber. The atomized feed solution coats fluidized particles passing through the desiccation/evaporation chamber. The coated fluidized particles are dried by a pre-heated gas stream and thereby creating fluid-bed particles that are coated with a layer of the XF.cndot.nH.sub.2O.sub.2 compound. The resulting XF.cndot.nH.sub.2O.sub.2 coated fluid-bed particles are then subjected to disintegration forces that serve to break substantial portions of the layer of dried XF.cndot.nH.sub.2O.sub.2 material from the outer surfaces of he individual fluid-bed particles. These dried XF.cndot.nH.sub.2O.sub.2 are then recovered as the product of these production methods.
