Abstract:
1. A method of making a substantially dried compound having the general formula XF•nH 2 O 2 wherein X is K + , Na + or NH 4+ and n is an integer from 1 to 3, said method comprising: (1) preparing a feed solution comprised of: (i) a fluid carrier component, (ii) a XF composition wherein X is K, Na (2) atomizing a portion of the feed solution as it enters a desiccation/evaporation chamber; (3) creating a fluid-bed of individual particles in the desiccation/evaporation chamber in order that the atomized portion of the feed solution entering said chamber coats outside surface areas of said individual particles; (4) passing a pre-heated gas stream through the desiccation/evaporation chamber such that said pre-heated gas stream: (5) separating a resulting, substantially dried XF•nH (6) collecting the substantially dried XF•nH
