Abstract
A granular explosive is obtained by mixing porous prill ammonium nitrate having an average particle size of 0.5 to 3.0 mm with a liquid aromatic dinitro compound and optionally a metal powder. Explosives having high sensitivity and power can be obtained by a simple and easy process.
Claims5
A method of preparing a granular explosive comprising porous prill ammonium nitrate having an average particle size of 0.5 to 3.0 mm a metal powder and an aromatic dinitro compound having a melting point of 50.degree. to 100.degree. C., said method comprising:
- melting said aromatic dinitro compound;
- mixing said porous prill ammonium nitrate with said melted aromatic dinitro compound;
- cooling the resultant mixture;
- and
- further mixing the cooled mixture with said metal powder.
