ABSTRACT:
A phase stabilized ammonium nitrate mixed crystal structure is produced by the addition of potassium fluoride. Thus the undesirable abrupt expansion and contraction of ammonium nitrate in the temperature range of use in rocket motor propellants and explosives (-55.degree. C. to .lambda..degree. C.) is eliminated. The mixture is made by the addition of between about 3% to 5% and preferably about 3.5% by weight potassium fluoride to the ammonium nitrate by a nonhazardous aqueous method.
