The stabilities of the blend nitrate ester and the high energetic binder containing 70% blend nitrate ester were studied by adding some impurities. The results indicate that the stability of nitrate ester is decreased with the addition of Fe³⁺，Cl^-,and particularly NO₃^-. The effects of Fe₂(SO4)₃，FeCl₃，Fe(NO₃)₃，BaCl₂ decreases in sequence on the stability of high energetic binder containing 70% blend nitrate ester,and high concentration of impurity causes low stability. At three different storage temperatures, the safety storage time of the high energetic binder increases firstly and then decreases with the increase of pH value,reaches its longest point at a pH value of 7.08. And the water content decrease the safety storage period,too.
