Abstract
Abstract A molten metal-liquid explosive device comprising: (1) a metal casing enclosing an inner space; (2) a fusable metal wall dividing the inner space into a liquid chamber and pyrotechnic material chamber; (3) a liquid (e.g., water) contained in the liquid chamber; (4) a pyrotechnic material essentially comprising an intimate mixture of (a) a magnesium nickel alloy hydride of the formula MgNi x H y wherein 0<×≦0.50 and 1.50≦y≦2.00 and (b) a oxidizer selected from the group consisting of CuO, Li 2 O 2 , BaO 2 , and mixtures thereof; wherein the molar ratio of oxidizer to magnesium nickel alloy hydride (MgNi x H y ) is from about 0.75:1 to about (1.50+0.5y):1 and wherein the pyrotechnic material is contained in the pyrotechnic material chamber in an amount sufficient to melt the fusable metal wall dividing the liquid chamber and the pyrotechnic material chamber; and (5) means for igniting the pyrotechnic material.
