Cook, M A; Balli, F K

An explosive composition in slurry or semi-solid form and containing calcium nitrate is made up by reacting calcium oxide with formaldehyde, preferably in the form of paraformaldehyde, in the presence of ammonium nitrate. The water generated in the reaction serves as a vehicle for the slurry. A thickener of gum or preferably starch is added, and gassing agents may be incorporated to control or reduce composition density. The presence of ammonium nitrate prevents runaway reactions and the hexamethylene-tetramine which is produced in the reaction serves as a fuel tending to give oxygen balance to the composition.
