An oxidized comprising a double salt represented by the chemical formula: M(NO 3 ) i nNH 4 NO 3 . 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. |
