Abstract
A water-in-oil emulsion explosive composition comprising a carbonaceous fuel, and inorganic oxidizer, an emulsifier, and a sensitizing/densifying agent of finely divided non-explosive material of high density, such as ferrophosphorus, ferrosilicon, ferromanganese, sand or alumia which is added to the oil phase. The water-in-oil composition can also contain other components, such as bulking agents, additional fuels and auxiliary sensitizers. The sensitized compositions can be detonated with a No. 6 cap in diameters as low as 2.54 centimeters at temperatures as low as 5.degree. F. and with densities as high as 1.50 g/cc.
