Abstract

Ammonium nitrate (AN) is a pos-sible replacement for ammonium perchlorate as an oxidizer in solid rocket motors potentially generat-ing large amounts of AN to be recycled or reused. AN requires phase stabilization before it can be used, so small amounts of potassium dinitrimide (KDN) are added to create phase stabilized ammonium nitrate (PSAN). Reuse alternatives would either require separating the KDN or destroying it. AN is commonly used as a fertilizer (80 percent of AN
