A substantially dried XF.nH<SUB>2</SUB>O<SUB>2 </SUB>product is produced by method(s) wherein a feed solution comprised of (i) a XF composition wherein X is K, Na<SUP>+</SUP> or NH<SUB>4</SUB><SUP>+</SUP> and n is an integer from 1 to 3, (ii) hydrogen peroxide (H<SUB>2</SUB>O<SUB>2</SUB>), (iii) a fluid carrier component and (iv) a potassium bifluoride (KHF<SUB>2</SUB>) 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.nH<SUB>2</SUB>O<SUB>2 </SUB>compound. The resulting XF.nH<SUB>2</SUB>O<SUB>2 </SUB>coated fluid-bed particles are then subjected to disintegration forces that serve to break substantial portions of the layer of dried XF.nH<SUB>2</SUB>O<SUB>2 </SUB>material from the outer surfaces of he individual fluid-bed particles. These dried XF.nH<SUB>2</SUB>O<SUB>2 </SUB>are then recovered as the product of these production methods.
