In order to research the chemical stability of ignition composition including metal powdery, the hygroscopicity experiments have been carried out for the ignition composition including some metals, such as magnesium, aluminium, etc.

The results show that the acceptable criterion for chemical stability of nitroglycerin is a concentration of NO_x of less than or equal to 85ppb/82℃, 11min.

The chemical stability is worse than the double base propellant.
