Abstract
Methods for the production of ammonium sulfate nitrate include (a) providing at a temperature of less than about 175° C. a melt including ammonium nitrate, ammonium sulfate, and water and the water content is greater than about 2 wt % based on the total weight of ammonium nitrate, ammonium sulfate and water in the melt, and (b) solidifying from the melt 1:2 ANS double salt by cooling at least a portion of the melt at a rate of less than about 100° C./min.
