A process for preparing free-flowing, phase-stabilized ammonium nitrate comprises the following steps. A solution of ammonium nitrate (12), a surfactant (13), a phase stabilizer (26), and an inert liquid (20) is prepared. The solution is atomized to form a stream of droplets. The droplets are freeze-dried to form agglomerates (54) of crystals of phase stabilized ammonium nitrate. The crystals of phase stabilized ammonium nitrate in the agglomerates are coated with a film comprising the surfactant. The agglomerates are disintegrated into separated free-fl...
1. A process for preparing a free-flowing, phase-stabilized ammonium nitrate, said process comprising the following steps:preparing a solution of ammonium nitrate, a surfactant, an inert liquid, and an ammonium nitrate phase stabilizer, said ammonium nitrate, said surfactant, and said phase stabilizer being soluble in said inert liquid, the amount of surfactant in said solution being about 0.01% to about 0.15% based on the combined weight of the ammonium nitrate and the surfactant; atomizing the solution to form a stream of droplets, the droplets having ...
