PROBLEM TO BE SOLVED: To provide a method for safely and inexpensively obtaining crystalline explosive which is poorly sensitive and is pulverized using a convenient equipment and to provide a producing method for obtaining a powdery gunpowder composition which is excellent in dispersibility and combination property of the crystalline explosive and the component other than the crystalline explosive. SOLUTION: A raw material of gunpowder composition such as trimethylene trinitramin is mixed with a good solvent such as methyl ethyl ketone, the crystalline explosive of one kind or more is dissolved in the good solvent by 20-98 wt.%, a suspension which completely dissolves the other components and is in the state of solid-liquid coexistence is allowed in contact with a poor solvent such as water to which the raw material of gunpowder composition is insoluble, thereby, the raw material of gunpowder composition is deposited and, as a result, the powdery gunpowder composition which contains the pulverized crystalline explosive which is controlled so as to be particulate is produced. |
