Double salt of ammonium nitrate, gas generating agent containing the same and production method thereof

摘要

An oxidized comprising a double salt represented by the chemical formula: M(NO3)inNH4NO3. M is a metal element forming a nitrate salt usually containing water of crystallization, i is a numerical value corresponding to the valency of the metal element M, and n is a molar number from 1 to 20. Mixing a metal nitrate containing water of crystallization with ammonium nitrate , and, further drying produces the above-mentioned double salt.
