摘要:
High surface area monolithic foams of essentially pure metal were prepared. Salts of the corresponding metal were prepared as loose powders, pressed into shapes, ignited under an inert atmosphere, and then heated under an atmosphere containing hydrogen to form nanostructured metal foam monoliths of essentially pure metal having a very high surface area.
摘要:
The present invention provides a compound of the formula (Cat)+z[M++(5-nitro-1H-tetrazolato-N2)−x(H2O)y] where x is 3 or 4, y is 2 or 3, x+y is 6, z is 1 or 2, and M++ is selected from the group consisting of iron, cobalt, nickel, copper, zinc, chromium, and manganese, and (Cat)+ is selected from the group consisting of ammonium, sodium, potassium, rubidium and cesium. A method of preparing the compound of that formula is also disclosed.
摘要:
Lead-free primary explosives of the formula (cat)Y[MII(T)X(H2O)6-X]Z, where T is 5-nitrotetrazolate, and syntheses thereof are described. Substantially stoichiometric equivalents of the reactants lead to high yields of pure compositions thereby avoiding dangerous purification steps.
