Bismuth-based energetic materials

A method for preparation of energetic compounds based on bismuth salts with reduced toxicity, having properties of primary explosives, said method comprising:

• preparing a suspension of soluble bismuth perchlorates by a reaction of bismuth oxide and perchloric acid;
• reacting said soluble bismuth perchlorates with water to form a solution;
• reacting said solution with soluble salts of organic or inorganic energetic compounds by a metathetical reaction forming a precipitate of bismuth energetic compounds;
• wherein the soluble salts of the organic or inorganic energetic compounds are based on azides, aromatic polynitro compounds, or derivatives thereof, or nitrogenous heterocyclic compounds, thereby forming a bismuth salt having a bismuth cation selected from the group consisting of Bi(3+), BiO(+), Bi(OH)2(+), Bi(OH)(2+), (BiO)5OH(4+), and Bi6O4(OH)4(6+) and an anion selected from the group consisting of inorganic azides, polynitro-phenols, polynitro-azido-phenols, derivatives of polynitro-diazo-chinones, polynitro-furoxanes and five-membered nitrogenous heterocycles or derivatives thereof.
