Claim 0:
1. A phase-stabilized ammonium nitrate (PSAN) prill comprising:
ammonium nitrate;
a porosity enhancing agent; and
a potassium salt, wherein the PSAN prill comprises from 2.1 mole percent (mol %) to 5 mol % potassium ions of the potassium salt based on the ammonium ions of the ammonium nitrate, wherein the potassium salt comprises at least one of potassium hydroxide, potassium nitrate, potassium sulfate, potassium hydrogen sulfate, potassium carbonate, or potassium hydrogen carbonate;
wherein the PSAN prill is explosive grade and has a bulk density less than 0.9 kg/L, and
wherein upon thermal cycling the PSAN prill 20 times, wherein one cycle comprises four hours at 15° C. followed by four hours at 45° C., an average crush strength of the thermal cycled PSAN prill is greater than an average crush strength of non-thermal cycled control PSAN prill.
